Recommended Products for This Recipe
After making this casserole countless times, I’ve found a few products that really make a difference in the final result.
1. Le Creuset Stoneware Baking Dish
This baking dish holds heat beautifully and gives you those perfectly bubbly, golden edges that make casseroles irresistible.
The stoneware distributes heat evenly, so you won’t end up with cold spots in the middle or burnt edges.
2. Lodge Cast Iron Skillet
A quality cast iron skillet is perfect for browning the ground beef. It gets incredibly hot and maintains that heat, which means better browning and more flavor development in your meat.
3. Frontera Gourmet Mexican Red Chile Enchilada Sauce
This enchilada sauce has authentic flavor with just the right amount of depth and spice.
It makes a noticeable difference compared to generic brands, adding layers of flavor to your casserole.
4. Cabot Mexican Blend Shredded Cheese
Quality shredded cheese melts better and tastes richer than pre-shredded alternatives.
This blend has the perfect ratio of cheeses for that authentic Tex-Mex flavor and stretchy, melty texture.
Step-by-Step Instructions: How to Make Tex Mex Casserole
Follow these detailed steps to create the perfect Tex-Mex casserole. Even if you’re new to cooking, you’ll find this process straightforward and rewarding.
1. Preheat and Prepare
- Preheat your oven to 350°F (175°C)
- Lightly grease your 9×13 inch baking dish with cooking spray or a thin layer of oil
- Set the baking dish aside while you prepare the filling
2. Brown the Ground Beef
- Heat your large skillet over medium-high heat
- Add the 2 lbs of ground beef to the hot skillet
- Break up the meat with your wooden spoon or spatula as it cooks
- Continue cooking for 8-10 minutes, stirring occasionally, until the beef is completely browned with no pink remaining
- Season with a pinch of salt and pepper to taste
3. Add the Onion and Seasoning
- Add the diced onion to the browned beef
- Cook for 3-4 minutes, stirring frequently, until the onion becomes soft and translucent
- Sprinkle the packet of taco seasoning over the beef and onion mixture
- Stir well to coat everything evenly with the seasoning
- Cook for another 2 minutes to let the spices bloom and become fragrant
4. Mix in the Beans and Sauces
- Add the can of refried beans to the skillet
- Stir until the refried beans are completely incorporated into the meat mixture

- Pour in the enchilada sauce and salsa
- Mix everything together thoroughly until you have a well-combined, saucy mixture
- Let it simmer on low heat for 3-5 minutes to allow the flavors to meld together
- Remove from heat
5. Layer the Casserole

- Spread half of the beef and bean mixture evenly over the tortillas
- Sprinkle 1 cup of the shredded Mexican cheese blend over the beef layer

Tips for The Best Tex Mex Casserole
These tips come from years of making this recipe and learning what works best. They’ll help you avoid common pitfalls and create the best possible casserole.
- Drain the beef properly: After browning the ground beef, drain off excess fat to prevent a greasy casserole. I usually tilt the pan and spoon out most of the fat, leaving just enough to keep things moist.
- Don’t skip the resting time: Letting the casserole rest for 5-10 minutes after baking makes a huge difference. The layers firm up slightly, making it much easier to cut clean portions.
- Warm your tortillas: If your tortillas are cold from the fridge, warm them slightly in the microwave for 15-20 seconds. This makes them more pliable and less likely to tear when layering.
- Use freshly shredded cheese: Pre-shredded cheese contains anti-caking agents that can affect melting. Shredding your own cheese from a block gives you that perfect, gooey texture.
- Mix the cheeses: I like to use a combination of cheddar, Monterey Jack, and a little queso quesadilla for the best flavor and melt.
- Layer evenly: Take your time to spread each layer evenly. This ensures every serving has the perfect ratio of tortillas, meat, and cheese.
- Adjust spice levels: Start with mild salsa and enchilada sauce if you’re serving kids. You can always add hot sauce at the table for those who want more heat.
Serving Suggestions
This casserole is hearty enough to serve as a complete meal, but these accompaniments take it to the next level.
Serve it with a simple side salad dressed with lime vinaigrette to balance the richness. I also love putting out bowls of extra toppings so everyone can customize their serving.
- Diced avocado or guacamole
- Additional sour cream
- Sliced jalapeños for heat lovers
- Chopped fresh tomatoes
- Sliced green onions
- Tortilla chips for scooping
- Mexican rice on the side
- Refried beans
- Fresh lime wedges
- Hot sauce or salsa verde

Variations of Tex Mex Casserole
One of the best things about this recipe is how adaptable it is. Here are some variations I’ve tried and loved.
- Chicken Tex-Mex Casserole: Replace the ground beef with 2 lbs of cooked, shredded chicken. Rotisserie chicken works perfectly and saves time.
- Vegetarian Version: Skip the meat entirely and double up on the beans. Add sautéed bell peppers, corn, and zucchini for extra vegetables and texture.
- Green Chile Version: Swap the enchilada sauce for green enchilada sauce and add a can of diced green chiles for a completely different flavor profile.
- Extra Spicy: Use hot salsa, add diced jalapeños to the beef mixture, and include some cayenne pepper with the taco seasoning.
- Corn Tortilla Version: Use corn tortillas instead of flour for a more authentic taste and gluten-free option. You may need a few more since corn tortillas are smaller.
- Breakfast Casserole: Add scrambled eggs to the layers and serve for brunch.
- Ground Turkey: Substitute ground turkey for a leaner option.
Storage and Reheating
This casserole stores beautifully, which makes it perfect for meal prep or enjoying leftovers throughout the week.
Store any leftover casserole in an airtight container in the refrigerator for up to 4 days. I usually cut it into individual portions first, which makes reheating much easier.
- Refrigerator Storage: Cover the baking dish tightly with plastic wrap or transfer portions to airtight containers. Keeps for 4-5 days.
- Freezer Storage: This casserole freezes wonderfully. Wrap individual portions in plastic wrap, then aluminum foil. Freeze for up to 3 months.
- Reheating from Fridge: Microwave individual portions for 2-3 minutes, or reheat in a 350°F oven for 15-20 minutes until heated through.
- Reheating from Frozen: Thaw overnight in the refrigerator, then reheat as directed above. Or microwave frozen portions for 4-5 minutes, stirring halfway through.
- Freshen up leftovers: Add fresh toppings like cilantro, sour cream, or avocado after reheating to make leftovers taste freshly made.

FAQs About Tex Mex Casserole
1. Can I make this casserole ahead of time?
Yes, you absolutely can prepare this casserole in advance. Assemble it completely through step 6, then cover tightly with plastic wrap and refrigerate for up to 24 hours.
When you’re ready to bake, remove from the refrigerator and let it sit at room temperature for 20-30 minutes.
Then bake as directed, adding an extra 5-10 minutes to the covered baking time since it’s starting cold.
2. Can I use corn tortillas instead of flour tortillas?
Corn tortillas work great in this recipe and give it a more authentic Tex-Mex flavor.
Since they’re typically smaller than flour tortillas, you’ll need about 15-18 corn tortillas to create the same coverage.
I recommend warming them slightly before layering so they’re more pliable and less likely to crack. The texture will be slightly different but equally delicious.
3. How can I make this casserole spicier?
There are several ways to add more heat to this dish. Use medium or hot salsa instead of mild, add diced jalapeños or serrano peppers to the beef mixture, or incorporate a can of diced green chiles.
You can also use spicy enchilada sauce or add a teaspoon of cayenne pepper or chipotle powder to the taco seasoning. Start conservatively and taste as you go.
4. What’s the best way to prevent a watery casserole?
The key to avoiding excess liquid is properly draining your ingredients and not overloading the sauce.
Make sure to drain the ground beef well after browning, and rinse and drain the black beans thoroughly.
If your mixture seems too wet after combining everything, let it simmer uncovered for a few extra minutes to reduce the liquid.
Also, don’t skip the resting time after baking, as this allows the layers to firm up.
5. Can I freeze this casserole before baking?
Yes, this casserole freezes beautifully before baking. Assemble it completely in a freezer-safe baking dish, then wrap it tightly with plastic wrap and aluminum foil.
Freeze for up to 3 months. When ready to bake, you can cook it directly from frozen (add 20-25 minutes to the covered baking time) or thaw overnight in the refrigerator and bake as directed.
