My sister first made this lemon ricotta pasta for a spring family get‑together, and it immediately became one of those back‑pocket recipes I rely on when I want something bright, comforting, and low‑effort. It’s essentially a baked riff on classic Italian lemon-ricotta sauces, but streamlined to four ingredients and finished in the oven so the noodles soak up all that tangy, creamy goodness. Everything happens in one casserole dish, and the result is a pan of sunny, gently browned pasta that feels special enough for company but easy enough for a Tuesday night.
Serve this lemon ricotta pasta straight from the glass casserole dish while it’s still hot and creamy. I like it with a simple green salad dressed in a sharp vinaigrette to balance the richness, plus a side of roasted or steamed spring vegetables like asparagus, peas, or broccoli. A crisp white wine such as Pinot Grigio or Sauvignon Blanc pairs nicely with the lemony notes, and a hunk of warm crusty bread is perfect for scooping up any sauce left in the pan.
Oven-Baked 4-Ingredient Lemon Ricotta PastaServings: 4
Ingredients
12 oz dried short pasta (such as penne, rigatoni, or fusilli)
1 1/2 cups whole-milk ricotta cheese
2 large lemons (zested and juiced, about 1/4 cup juice and 2 tbsp zest total)
1 cup finely grated hard cheese (such as Parmesan or Pecorino Romano)
1 1/2 tsp kosher salt, plus more to taste
1/2 tsp freshly ground black pepper (optional, but recommended)
1/2–3/4 cup reserved hot pasta cooking water (as needed for creaminess)
Olive oil or softened butter for greasing the baking dish
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 2-quart glass casserole dish with a little olive oil or softened butter. This keeps the pasta from sticking and helps with cleanup.
Bring a large pot of well-salted water to a boil. Add the pasta and cook until just shy of al dente, 1–2 minutes less than the package directions. The pasta will finish cooking in the oven, so you want it slightly underdone at this stage.
While the pasta cooks, make the lemon-ricotta mixture. In a large bowl, combine the ricotta, lemon zest, lemon juice, grated hard cheese, 1 1/2 teaspoons kosher salt, and black pepper if using. Stir until smooth and creamy. Taste and adjust seasoning; it should be assertively lemony and well salted.
Before draining the pasta, carefully ladle out about 1 cup of the hot pasta cooking water and set it aside. Drain the pasta well.
Add the hot, drained pasta directly to the bowl with the lemon-ricotta mixture. Toss gently to coat, adding 1/2 cup of the reserved pasta water to loosen the sauce. The mixture should look creamy and slightly loose; if it seems too thick or dry, add a splash more pasta water a little at a time.
Transfer the coated pasta into the prepared glass casserole dish, spreading it into an even layer. Use the back of a spoon to tuck any exposed noodles into the sauce so they don’t dry out in the oven.
Place the casserole dish on the middle rack and bake for 18–22 minutes, until the edges are bubbling, the top looks just set, and you see a few golden spots. The pasta should be tender but not mushy, and the sauce thickened but still creamy.
Remove the dish from the oven and let the pasta rest for 5–10 minutes. This brief rest allows the sauce to settle and cling to the noodles instead of running when you scoop it.
Just before serving, give the pasta a gentle stir from the edges toward the center to pull some of the saucy bits from the sides back into the middle. Serve directly from the glass casserole dish, using a large spoon to lift out generous, creamy scoops.
Variations & Tips
To keep the spirit of a bright, four-ingredient spring dish, think of additions as accents rather than a full rewrite. For a bit of green, scatter a handful of thawed frozen peas or blanched asparagus tips over the top before baking. If you enjoy a touch of heat, add a pinch of red pepper flakes to the lemon-ricotta mixture. For extra richness, drizzle a tablespoon of olive oil over the pasta just before it goes into the oven, or dot the top with a few small pieces of butter. You can also play with the cheese: Parmesan will give you a nutty, mellow flavor, while Pecorino Romano makes the dish saltier and more assertive—adjust the added salt accordingly. If you need to make this ahead, assemble the pasta and sauce in the dish, cover, and refrigerate for up to 8 hours; add a splash of milk or water before baking to loosen the sauce, and expect to add 5–10 minutes to the bake time. For food safety, keep the ricotta refrigerated until you’re ready to mix it, don’t leave the assembled unbaked dish at room temperature for more than 1–2 hours, and refrigerate leftovers within 2 hours of baking. Reheat leftovers in a covered dish at 325°F (165°C) until hot throughout, adding a spoonful of water or milk to restore creaminess.
