Pin it
When the temperature drops, I want a dinner that feels like a blanket. This ravioli lasagna delivers that without the usual work. Frozen cheese ravioli stand in for traditional noodles, so you skip the boil and get built-in cheese pockets in every layer.
The fall twist comes from butternut squash pureed into the ricotta layer and sweet Italian sausage browned with sage. It bakes into something creamy, savory, and just sweet enough to feel seasonal. You can assemble it earlier in the day and bake it when you are ready.
What builds the layers
A short list that rewards quality. Use a good jar of marinara and whole milk ricotta rather than part-skim, which can get grainy when it bakes.
- Frozen cheese ravioli. They act as noodle and cheese layer in one shortcut, and they hold their shape without pre-boiling.
- Sweet Italian sausage. Adds fall herbs and enough fat to flavor the whole dish as it bakes.
- Butternut squash puree. Brings earthy sweetness and a creamy orange color to the ricotta layer.
- Whole milk ricotta. Lightens into a fluffy filling with egg and nutmeg.
- Marinara sauce. Ties the layers together with acidity so the richness does not overwhelm.
- Mozzarella and Parmesan. The melt and the sharp finish that makes every slice stretch.
- Fresh sage and nutmeg. The warm spice combination that makes it taste like autumn.
- Egg. Binds the ricotta so it slices cleanly instead of oozing.
How to layer and bake
- Brown the sausage. Cook the sausage with onion, garlic, and sage in a hot skillet until no pink remains, about 6 to 8 minutes. Drain off excess fat so the bake stays clean, then stir in the marinara sauce.
- Mix the squash ricotta. Stir the butternut squash puree with ricotta, egg, parmesan, nutmeg, salt, and pepper until smooth and evenly orange.
- Sauce the dish. Spread a thin layer of the meat sauce on the bottom of a 9 by 13 inch baking dish so nothing sticks.
- Layer twice. Arrange half the frozen ravioli in a single layer. Dollop half the ricotta mixture over the top, then scatter half the sausage sauce and sprinkle with mozzarella. Repeat the layers once more.
- Bake covered then uncovered. Cover tightly with foil and bake at 375°F for 30 minutes. Remove the foil, add the remaining mozzarella, and bake 10 to 15 minutes more until the top is browned and bubbling. Let rest 10 minutes before serving.
Why ravioli wins over noodles
Traditional lasagna requires boiling long noodles, then layering them carefully so they do not tear. Frozen ravioli skips all of that. They are pre-cooked, filled with cheese, and sturdy enough to stack. Each bite gives you pasta plus an extra pocket of ricotta inside. If you enjoy this shortcut, our million dollar ravioli casserole uses the same trick with a different flavor profile.
The squash that sweetens the sauce
I prefer butternut squash pureed into the ricotta rather than cubed, because it blends into a smooth layer that does not disrupt the slice. It adds body, fiber, and a subtle sweetness that pairs with sage and sausage. You can roast and blend your own or use canned puree from a solid brand. For more ideas with this vegetable, see this butternut squash recipe gallery. If you like the squash and sausage combination, our butternut squash sausage tortellini soup uses the same pairing in a bowl.
Assemble ahead and freeze
You can build the layers in the morning, cover the dish, and refrigerate it until dinner. Bake straight from the fridge and add about 10 minutes to the covered time. To freeze, wrap the unbaked dish tightly in two layers of foil and freeze up to 2 months. Thaw overnight in the refrigerator before baking. This makes it a solid choice for busy weeks when you want something better than takeout.
What to serve on the side
A crisp green salad with apple cider vinaigrette cuts the richness. Add crusty bread for scooping up any sauce that pools on the plate, or roast a tray of Brussels sprouts with olive oil and salt while the lasagna bakes. For a creamy white sauce variation on the same idea, try our sausage alfredo ravioli lasagna.
FAQs
- Can I use frozen ravioli straight from the freezer?
Yes. Layer them while still frozen. They will thaw as the dish bakes. Add 5 to 10 minutes to the covered baking time to make sure the center is hot all the way through.
- What can I substitute for butternut squash?
Canned pumpkin puree works in the same amount. Do not use pumpkin pie filling, which contains sugar and spice. Roasted and mashed sweet potato is another good swap that keeps the orange color and sweetness.
- How do I store and reheat leftovers?
Cover the dish tightly and refrigerate up to 4 days. Reheat individual portions in the microwave or the whole dish in a 350°F oven until warmed through, about 20 minutes.
- Can I use ground beef instead of Italian sausage?
Yes, but add a teaspoon of fennel seeds and half a teaspoon of dried sage to mimic the sausage flavor profile. Drain the meat well after browning so the bake does not get greasy.
- What size baking dish should I use?
A 9 by 13 inch dish works best. It holds two full layers without overflowing and gives you the best ratio of crispy top to creamy center.
- Why did my ravioli lasagna turn out watery?
Too much sauce, undrained sausage, or skipping the rest time are the usual causes. Use thin sauce layers, drain the meat, and let the pan sit for 10 minutes after baking so the layers set before you cut.
- Can I make this in a slow cooker?
Yes, though the texture is softer. Layer the same way and cook on low for 4 hours. If you prefer that method, our crockpot ravioli lasagna is built for it.
