My sister makes this every Sunday and the family goes absolutely crazy for it

My sister has been making this oven baked 4-ingredients lazy lasagna noodles every Sunday for as long as I can remember, and the family still crowds around the kitchen like it’s the first time. It started years ago when money was tight and time was even tighter after church, and she needed something that tasted like a big, proper lasagna without all the fuss of boiling noodles and building perfect layers. This version uses wide lasagna noodles, jarred marinara, ricotta, and mozzarella—nothing fancy, just what you can grab at any small-town grocery. It bakes up in a glass dish with bubbly cheese and saucy edges, and when it comes out of the oven, everyone “goes absolutely crazy for it,” as my grandkids like to say.

Serve this lazy lasagna straight from the glass baking dish with a big spoon so everyone can scoop out their own cheesy corner. It pairs nicely with a simple green salad dressed with vinegar and oil, or a bowl of cottage cheese and sliced tomatoes if you grew up in the Midwest like we did. Warm garlic bread or buttered toast is perfect for mopping up the extra marinara, and a side of steamed green beans or corn completes the kind of Sunday supper that makes the house feel full and content.

Servings: 6-8

12 dry lasagna noodles (wide, uncooked)

Preheat your oven to 375°F (190°C). Set out a 9x13-inch glass baking dish so it’s ready to layer.

Spread about 1 cup of marinara sauce over the bottom of the glass baking dish, just enough to lightly coat it so the noodles don’t stick.

Lay 4 dry lasagna noodles over the sauce in a single layer, breaking a noodle if needed to fit your dish. They can overlap a little; they will soften as they bake.

Drop spoonfuls of about 1 cup ricotta over the noodles and gently spread it into an even layer with the back of a spoon. It doesn’t have to be perfect; little pockets of ricotta are part of the charm.

Sprinkle 1 cup of shredded mozzarella evenly over the ricotta layer.

Pour about 1 1/2 cups of marinara sauce over the cheese and spread it out so it covers the noodles and cheese. Make sure the noodles are well-sauced; this moisture helps them cook through in the oven.

Repeat the layers two more times: noodles, ricotta, mozzarella, then sauce. You should end with a generous layer of marinara on top, making sure all noodle edges are covered so they don’t dry out.

Finish by sprinkling the remaining mozzarella cheese over the very top so it will melt and bubble as it bakes.

Cover the baking dish tightly with foil, tenting it slightly so it doesn’t press into the cheese. Place the dish on the middle rack of the preheated oven.

Bake covered for 35–40 minutes, until the sauce is bubbling around the edges and the noodles are just tender when you slide a knife into the center.

Carefully remove the foil (watch for hot steam), then return the dish to the oven and bake uncovered for another 10–15 minutes, or until the top is golden in spots and the cheese is fully melted and lightly browned.

Remove the lasagna from the oven and let it rest on the counter for at least 10–15 minutes before serving. This rest time helps it set up so it scoops neatly instead of sliding apart.

Scoop generous portions straight from the glass dish and serve hot. Store leftovers, once cooled, covered in the refrigerator and reheat thoroughly before eating.

If you want to stretch this into a heartier Sunday meal, you can tuck cooked and drained ground beef or Italian sausage between the layers along with the ricotta, though that will technically add more than four ingredients. For a touch of freshness, you can stir a handful of chopped fresh basil or parsley into the marinara before layering, or sprinkle dried Italian seasoning over the top before baking. If your family likes extra cheesiness, add a little grated Parmesan on top of the mozzarella for the last 10–15 minutes of baking. For a slightly lighter version, you may use part-skim ricotta and mozzarella, but whole-milk cheeses melt more smoothly and give that classic Midwestern comfort-food richness. If your marinara sauce is very thick, thin it with a few tablespoons of water so the dry noodles have enough liquid to cook; dry spots can leave the noodles tough. Always make sure the noodles are fully covered in sauce—exposed edges can become hard and overbrowned. Bake until the center is piping hot and the sauce is bubbling to ensure it’s heated safely all the way through, especially if you’ve added meat. Leftovers should be cooled, covered, and refrigerated within 2 hours of baking, then reheated until steaming hot before serving again. This lasagna also freezes well: cool completely, wrap tightly, and freeze for up to 2–3 months; reheat covered in a 350°F (175°C) oven until hot in the center.
