Ingredients
You only need a short list of good ingredients to make this casserole shine.
Using Yukon Gold potatoes specifically makes a noticeable difference because of their naturally buttery, creamy texture once baked.
- 4 medium Yukon Gold potatoes, thinly sliced (about 1/8-inch thick)
- 8 large eggs
- 1 cup whole milk
- 2 cups shredded cheddar cheese
- 1/2 cup diced yellow onion
- 2 cloves garlic, minced
- 2 tbsp olive oil
- 1 tsp smoked paprika
- 1 tsp salt
- 1/2 tsp black pepper
Bacon Egg and Cheese Breakfast Casserole is another fantastic option if you want to change things up with smoky bacon layers.
Kitchen Equipment Needed
You do not need any special equipment for this recipe. Most of these tools are standard kitchen staples, though a sharp mandoline makes slicing the potatoes much quicker and more uniform.
- 9×13 inch baking dish
- Mandoline slicer or sharp knife
- Large mixing bowl
- Whisk
- Small skillet or saucepan
- Cutting board
- Measuring cups and spoons
- Aluminum foil
- Cooking spray or butter (for greasing the dish)
Recommended Products for This Recipe
These are tools and ingredients I personally love and return to when making this casserole. They genuinely make the cooking experience smoother and the results even better.
1. OXO Good Grips Mandoline Slicer
A mandoline makes slicing potatoes to an even 1/8-inch thickness quick and consistent, which is key to getting every layer cooked through at the same rate.
Uneven slices lead to some pieces being undercooked while others turn mushy. This is one of those tools that pays for itself the first time you use it.
2. Le Creuset Enameled Baking Dish
A quality ceramic or enameled baking dish distributes heat evenly so the bottom layer of potatoes cooks just as gently as the top.
It also goes from oven to table beautifully, which is a big plus when you are serving guests. The non-stick surface makes cleanup much easier after all that melted cheese.
3. Tillamook Sharp Cheddar Cheese Block
Pre-shredded cheese has added starches that can affect how smoothly it melts. Buying a block of sharp cheddar and shredding it yourself gives you that gooey, uninterrupted melt that makes this casserole so irresistible.
Tillamook sharp cheddar in particular has a bold, tangy flavor that stands up beautifully to the potatoes and eggs.
4. Penzeys Smoked Paprika
The smoked paprika in this recipe is not just a background note. It adds a gentle, woodsy warmth that makes the egg custard taste richer and more complex.
Quality smoked paprika from a reputable spice brand makes a real difference here compared to a grocery store variety that has been sitting on the shelf for two years.
Step-by-Step Instructions: How to Make Cheesy Potato Breakfast Casserole
1. Preheat the Oven and Prepare the Baking Dish
- Set your oven to 375°F (190°C) and allow it to fully preheat before the casserole goes in. A properly preheated oven ensures the potatoes begin cooking immediately and evenly from the start.
- Grease your 9×13 inch baking dish thoroughly with cooking spray or a thin layer of softened butter. Make sure to coat the sides and corners as well so nothing sticks.
- Set the prepared dish aside while you work on the rest of the recipe.
2. Slice the Potatoes
- Wash and scrub the 4 medium Yukon Gold potatoes well under cold water. There is no need to peel them since the skin is thin, tender, and adds a little rustic texture. However, you can peel them if you prefer a smoother result.
- Using a mandoline slicer set to 1/8 inch, or a sharp knife, slice each potato into very thin rounds. Aim for uniformity as much as possible. Thick slices will not cook through in time, and too-thin slices may fall apart.
- Place the sliced potatoes in a bowl of cold water as you work. This helps remove excess starch and keeps them from browning. Let them soak for about 5 minutes, then drain thoroughly and pat dry with paper towels. Removing the moisture is important so the casserole does not turn watery.
3. Sauté the Onion and Garlic
- Heat 2 tablespoons of olive oil in a small skillet over medium heat. Wait until the oil shimmers before adding the aromatics.
- Add the 1/2 cup of diced yellow onion to the pan. Stir occasionally and cook for about 3 to 4 minutes until the onion becomes soft and slightly translucent. You are not trying to brown it deeply, just soften it and take the raw edge off.
- Add the 2 cloves of minced garlic to the pan and stir it into the onions. Cook for just 30 to 60 seconds, stirring constantly. Garlic cooks fast and burns easily, so watch it closely. Once it smells fragrant, remove the pan from the heat immediately.
- Set the sautéed onion and garlic mixture aside to cool slightly.
4. Make the Egg Custard Mixture
- Crack all 8 eggs into a large mixing bowl. Beat them well with a whisk until the yolks and whites are fully combined and the mixture looks uniform in color.
- Pour in the 1 cup of whole milk and continue whisking until everything is well blended. Whole milk gives the custard a richer, creamier result compared to lower-fat options.
- Add 1 teaspoon of smoked paprika, 1 teaspoon of salt, and 1/2 teaspoon of black pepper. Whisk again to distribute the seasoning evenly throughout the egg mixture.
- Add the cooled sautéed onion and garlic to the egg mixture and stir to combine. These aromatics will flavor the entire custard as the casserole bakes.
5. Layer the Casserole
- Arrange about one-third of the sliced potatoes in a single, slightly overlapping layer on the bottom of the greased baking dish. Think of it like layering a lasagna. The slices should mostly cover the entire bottom with just slight overlap.
- Sprinkle approximately 2/3 cup of shredded cheddar cheese evenly over this first potato layer.
- Add another layer of potato slices on top of the cheese, again overlapping slightly.
- Sprinkle another 2/3 cup of cheddar cheese over the second potato layer.
- Add the final layer of potato slices on top.
- Pour the egg custard mixture slowly and evenly over the entire casserole. Pour it around the edges too, not just down the center, so it soaks through all the layers. Give the dish a gentle shake or press the potatoes down lightly with a fork to help the custard settle between the layers.
- Scatter the remaining 2/3 cup of shredded cheddar cheese over the very top of the casserole in an even layer.
6. Cover and Bake
- Cover the baking dish tightly with aluminum foil. This traps steam inside the dish, which helps the potato layers cook through evenly and prevents the top from browning too quickly before the inside is done.
- Place the covered dish on the center rack of your preheated 375°F oven.
- Bake covered for 35 minutes. During this time, the potatoes will steam and soften, and the egg custard will begin to set.
7. Uncover and Finish Baking
- After 35 minutes, carefully remove the foil using oven mitts. Be cautious as steam will escape when you lift the foil. Tilt it away from you to avoid getting burned.
- Return the uncovered casserole to the oven and bake for an additional 15 to 20 minutes. You are looking for the cheese on top to be melted, bubbly, and golden brown, and the egg custard to be fully set in the center.
- To test for doneness, insert a knife or toothpick into the center of the casserole. It should come out clean with no runny egg around it. If it is still wobbly in the middle, give it another 5 minutes.
8. Rest and Serve
- Remove the casserole from the oven and let it rest for at least 10 minutes before cutting into it. This resting period allows the egg custard to fully firm up so the slices hold their shape when served.
- Use a sharp knife or spatula to cut the casserole into squares. A spatula with a thin, flat edge works best for serving clean, neat portions.
- Serve warm and enjoy immediately. Optionally, garnish with fresh chopped chives, parsley, or a small dollop of sour cream for extra richness.
I use the same layering technique from my Croissant Breakfast Casserole, and it works like a charm every time.
Tips for The Best Cheesy Potato Breakfast Casserole
A few small adjustments make a real difference between a good casserole and an absolutely outstanding one. Keep these tips in mind and your result will be consistently perfect every time.
- Slice potatoes as uniformly as possible. Uneven thickness means some pieces will be overdone while others stay underdone. A mandoline is your best friend here.
- Dry the potato slices thoroughly. After soaking in cold water, pat them completely dry. Excess moisture leads to a watery casserole instead of a creamy one.
- Shred your own cheese. Pre-packaged shredded cheese contains anti-caking agents that prevent it from melting as smoothly. A freshly grated block melts better and gives you that gooey, stretchy texture.
- Do not skip the resting time. Ten minutes of resting after baking is non-negotiable if you want clean slices that hold together.
- Make it overnight. Assemble the casserole the night before, cover it with plastic wrap, and refrigerate. In the morning, bring it to room temperature for 20 minutes, then bake as directed. This actually improves the flavor as the custard soaks into the potato layers.
- Season generously. Potatoes need a good amount of salt to taste their best. Taste your egg mixture before pouring it in and adjust seasoning if needed.

Serving Suggestions
This casserole is hearty enough to stand on its own, but it pairs wonderfully with a few simple sides that round out a full breakfast or brunch spread.
A bowl of fresh fruit or a simple green salad cuts through the richness of all that cheese and egg beautifully.
You can also serve it alongside something sweet for a classic sweet-savory brunch spread.
Here are some great things to serve alongside this casserole:
- Fresh fruit salad or a simple berry bowl
- Banana Pancakes for a sweet complement to the savory casserole
- A side of crispy bacon or breakfast sausage links
- Avocado Toast for something fresh and creamy on the side
- Hot coffee, orange juice, or a pitcher of Pink Lemonade for a fun brunch drink
- A simple green salad dressed with lemon and olive oil
- Sour cream and fresh chives for topping directly at the table
Variations of Cheesy Potato Breakfast Casserole
Once you have the base recipe down, it is easy to switch things up based on what you have in the fridge or the preferences of your crowd.
- Add breakfast meat. Stir in 1 cup of cooked, crumbled breakfast sausage, diced ham, or crumbled bacon between the potato layers for extra protein and smoky flavor.
- Add vegetables. Diced bell peppers, sliced mushrooms, baby spinach, or diced jalapeños are all wonderful additions. Sauté them briefly with the onion and garlic before adding to the egg mixture.
- Try different cheeses. Swap some or all of the cheddar for Gruyère, Monterey Jack, pepper jack, or a smoked gouda for a completely different flavor profile.
- Make it spicy. Add a pinch of cayenne pepper or red pepper flakes to the egg mixture, or use pepper jack cheese instead of cheddar.
- Lighter version. Substitute the whole milk for 2% milk and reduce the cheese to 1.5 cups. The casserole will still be delicious, just a bit lighter.
- Use sweet potatoes. Replace the Yukon Golds with thinly sliced sweet potatoes for a slightly sweet, nutrient-packed twist. The baking time remains roughly the same.
Spinach and Feta Breakfast Casserole is a wonderful vegetarian variation if you want something lighter and Mediterranean-inspired.
Storage and Reheating
This casserole stores really well, which makes it one of the best options for meal prepping your breakfasts for the week. A few days in, it tastes just as good as it did fresh out of the oven.
- Refrigerator: Let the casserole cool completely, then cover the baking dish tightly with plastic wrap or foil, or transfer individual portions to airtight containers. It will keep in the refrigerator for up to 4 days.
- Freezer: Cut the fully cooled casserole into individual portions and wrap each piece tightly in plastic wrap, then place in a zip-top freezer bag. Freeze for up to 2 months. Label with the date so you remember when it was made.
- Reheating from the fridge: Place a portion on a microwave-safe plate and microwave on high for 1 to 2 minutes, or until heated through. Alternatively, reheat in a 350°F oven covered with foil for 15 to 20 minutes.
- Reheating from frozen: Thaw overnight in the refrigerator before reheating, then follow the same instructions above. Do not microwave straight from frozen as it can make the eggs rubbery.
- Make-ahead tip: Assemble the unbaked casserole up to 24 hours in advance, cover with plastic wrap, and refrigerate. Add 5 to 10 extra minutes to the covered baking time if going straight from the fridge to the oven.

FAQs About Cheesy Potato Breakfast Casserole
1. Can I use a different type of potato?
Yes, you can. Russet potatoes are the next best option and will give a slightly fluffier, more starchy texture.
Red potatoes also work and hold their shape very well. Yukon Golds are recommended because of their naturally buttery flavor and creamy texture, but any waxy or all-purpose potato will do the job.
2. Can I make this casserole the night before?
Absolutely, and it is actually one of the best things about this recipe. Assemble everything in the baking dish, cover it tightly with plastic wrap, and refrigerate overnight.
The next morning, let it sit at room temperature for about 20 minutes before putting it in the oven. This allows it to bake more evenly without the dish being ice cold when it goes in.
3. My casserole turned out watery. What went wrong?
This usually happens because the potato slices were not dried thoroughly enough after soaking, or the casserole was cut into before it had time to rest and firm up.
Make sure to pat the potato slices dry with paper towels before layering, and always let the finished casserole rest for at least 10 minutes before slicing.
4. Can I add meat to this casserole?
Yes, and it is a great way to make it even more filling. Cooked, crumbled breakfast sausage is the most popular addition.
Diced ham and crumbled bacon are also wonderful. Add the cooked meat between the potato layers during assembly, just as you would add the cheese.
Make sure any meat is fully cooked before it goes in, since the casserole baking time is not long enough to cook raw meat safely.
5. How do I know when the casserole is done?
The top should be golden and bubbly, and the center should not jiggle when you gently shake the dish.
You can also insert a thin knife or skewer into the middle of the casserole. If it comes out clean with no wet egg around it, the casserole is fully set and ready to come out of the oven.

Notes
- Make ahead: Assemble the unbaked casserole up to 24 hours in advance, cover with plastic wrap, and refrigerate. Let it sit at room temperature for 20 minutes before baking, and add 5 to 10 extra minutes to the covered bake time.
- Dry the potatoes thoroughly: After soaking, pat the potato slices completely dry with paper towels. Excess moisture is the main cause of a watery casserole.
- Shred your own cheese: Pre-shredded cheese contains anti-caking starches that prevent smooth melting. Freshly grated block cheddar gives you a gooier, more even melt.
- Do not skip resting time: Waiting 10 minutes after baking allows the custard to firm up so slices hold their shape cleanly when served.
- Add protein: Stir 1 cup of cooked, crumbled breakfast sausage, diced ham, or crumbled bacon between the potato layers for extra heartiness.
- Add vegetables: Diced bell peppers, sliced mushrooms, baby spinach, or jalapeños work beautifully — sauté them briefly with the onion and garlic before adding to the egg mixture.
- Cheese swaps: Try Gruyère, Monterey Jack, pepper jack, or smoked gouda in place of cheddar for a different flavor profile.
- Storage: Cool completely, then cover and refrigerate for up to 4 days, or freeze individual portions wrapped tightly for up to 2 months.
- Reheating: Microwave individual portions on high for 1 to 2 minutes, or reheat covered in a 350°F oven for 15 to 20 minutes. Thaw frozen portions overnight in the fridge before reheating.
- Potato substitutions: Russet or red potatoes both work well. Russets give a fluffier texture; reds hold their shape a bit more firmly.
