This Creamy Spinach Ricotta Pasta is a silky, satisfying weeknight dinner that comes together in just 30 minutes with simple pantry staples.

It's naturally vegetarian, endlessly adaptable, and guaranteed to become one of your most-requested dinners.
Equipment
- Large pasta pot At least 6-quart capacity
- Large skillet or sauté pan 12-inch recommended
- Colander For draining pasta
- Ladle or heatproof measuring cup For reserving pasta water
- Wooden spoon or silicone spatula
- Microplane zester or box grater For Parmesan and lemon zest
- Chef's knife and cutting board For mincing garlic
Ingredients
- 12 oz rigatoni, penne, or spaghetti pasta 340g; any short or long pasta shape works
- 1 tablespoon olive oil
- 4 cloves garlic minced
- 5 oz baby spinach 140g, fresh
- 1 cup whole-milk ricotta cheese 250g; part-skim works but whole-milk gives a creamier result
- 1/2 cup freshly grated Parmesan cheese 50g; plus more for serving; grate from a block for best melt
- 1/2 teaspoon lemon zest optional but recommended; from about half a lemon
- 1 tablespoon fresh lemon juice from about half a lemon
- 1/4 teaspoon ground nutmeg
- salt to taste; use generously in pasta water
- black pepper to taste, freshly cracked
- 3/4 cup reserved pasta cooking water about 180ml; reserve before draining pasta
For Serving
- extra Parmesan cheese freshly grated
- red pepper flakes optional, for heat
- extra virgin olive oil for drizzling
Instructions
- Fill a large pot with 4 to 5 quarts of cold water and bring to a full rolling boil over high heat. Season generously with salt until the water tastes like light broth.
- Add the pasta and cook 1 to 2 minutes less than the package directions for al dente, stirring occasionally. Before draining, scoop out at least 1 cup of starchy pasta water and set aside, then drain the pasta without rinsing.
- Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the minced garlic and sauté for 1 to 2 minutes until fragrant and lightly golden, being careful not to let it burn.
- Add all the fresh baby spinach to the skillet and toss with the garlic oil. Cook for 2 to 3 minutes, stirring frequently, until fully wilted and bright green, then season lightly with salt and pepper.
- Reduce heat to low and add the ricotta along with 1/2 cup of the reserved pasta water. Stir until smooth and creamy, then mix in the nutmeg, lemon zest, and lemon juice, adding more pasta water as needed to reach a silky consistency.
- Stir in the grated Parmesan until fully melted, then add the drained pasta and toss to coat thoroughly. Add more pasta water a splash at a time if the sauce is too thick, tossing until glossy and well combined.
- Divide among four bowls and top with extra Parmesan, a drizzle of olive oil, a crack of black pepper, and red pepper flakes if desired. Serve immediately.
Notes
- Use whole-milk ricotta for the creamiest sauce — part-skim has more water content and a slightly grainy texture that doesn't melt as smoothly.
- Never skip reserving pasta water; the starch is what emulsifies the ricotta into a cohesive, silky sauce rather than a chunky one.
- Grate Parmesan fresh from a block — pre-grated contains anti-caking agents that prevent smooth melting.
- If using frozen spinach, thaw completely and squeeze out all excess moisture before adding to the pan or the sauce will become watery.
- Cook pasta 1 to 2 minutes less than the package time — it will finish cooking briefly in the sauce and absorb flavor as it does.
- Don't brown the garlic; you want it golden and fragrant. Burnt garlic turns bitter and will affect the entire dish.
- Add pasta water gradually — a tablespoon or two at a time — to control the sauce consistency without making it too thin.
- Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently over low heat with a splash of water to loosen the sauce. Do not freeze — ricotta-based sauces separate when thawed.
- To add protein, stir in shredded rotisserie chicken, sautéed Italian sausage, or pan-seared shrimp before tossing with the pasta.
- For a spicy version, add 1/2 teaspoon of red pepper flakes to the oil with the garlic at the start of cooking.
