Ingredients You'll Need

The first pot is filled with a thick reddish-brown meat sauce with visible chunks of ground meat and small pieces of tomato, stirred by a wooden spoon. The second pot contains the same meat sauce mixed with short, hollow pasta that is light yellow and slightly curved, coated evenly by the sauce. The sauce and pasta blend gives a textured and hearty look with a mix of red, brown, and yellow tones. photo taken with an iphone --ar 4:5 --v 7

Each ingredient in this Lazy Lasagna Casserole Recipe plays an essential role in delivering that irresistible blend of flavors and textures – from the perfectly cooked pasta to the creamy ricotta and savory meat sauce.

  • 10 ounces campanelle: Short pasta shapes like campanelle or penne hold the sauce beautifully, making every bite satisfying.
  • 1 pound lean ground beef: Adds hearty protein and a rich, meaty base for the sauce.
  • ½ cup diced onion: Brings sweetness and depth to the savory beef mixture.
  • 1 teaspoon minced garlic (divided): Infuses aromatic flavor that complements the meat and cheese perfectly.
  • 1 teaspoon Italian seasoning: A blend of herbs that enhances the classic Italian taste.
  • ½ teaspoon salt: Balances and brightens all the savory flavors.
  • ½ teaspoon pepper (divided): Adds mild spiciness to keep the flavor lively without overpowering.
  • 25 ounces marinara sauce: Choose a good quality sauce for a robust, tangy tomato backdrop.
  • ¼ cup water: Helps thin the sauce slightly, ensuring everything blends smoothly.
  • 1 cup part-skim ricotta cheese: Creamy and mild, it adds luscious texture and richness.
  • 1 egg: Binds the ricotta mixture, giving it a nice, firm consistency when baked.
  • 3 cups shredded part-skim mozzarella cheese (divided): Melts beautifully on top and within the casserole for that gooey, cheesy goodness.
  • ½ cup grated Parmesan cheese (divided): Adds savory, nutty sharpness to elevate the cheese blend.
  • 1 teaspoon dried parsley flakes (or 1 tablespoon fresh): Brightens the dish with a hint of herbal freshness.
  • Fresh basil (optional for garnish): Adds a pop of color and fresh flavor to finish the dish beautifully.

How to Make Lazy Lasagna Casserole Recipe

Step 1: Cook the Pasta

Start by boiling the campanelle pasta, but only cook it one minute less than the package directs. This ensures the pasta will finish cooking in the oven without becoming mushy. Once done, drain the pasta well and set it aside—this simple preparation will give you perfectly tender noodles that soak up all the delicious sauce.

Step 2: Prepare the Meat Sauce

While the pasta cooks, brown the ground beef along with diced onion and half of your minced garlic in a large skillet or Dutch oven. Cooking the beef until no pink remains develops rich flavor, while the onions soften and sweeten the mix. After draining off excess grease, season the meat with Italian seasoning, salt, and a little pepper. Stir in the marinara sauce along with a splash of water, then simmer for a few minutes to marry the flavors before folding in the cooked pasta. This hearty, savory mixture is the foundation of your Lazy Lasagna Casserole Recipe.

Step 3: Prepare the Ricotta Mixture

In a large bowl, whisk together the ricotta cheese and egg until smooth. This binds the cheese so it holds up well in the casserole. Next, mix in half of the shredded mozzarella, remaining garlic, half of the Parmesan cheese, parsley flakes, and the rest of the pepper. This creamy, flavorful layer adds delightful texture and richness to balance the robust meat sauce.

Step 4: Assemble the Casserole

Preheat your oven to 350°F and coat a 13x9 inch baking dish with non-stick spray to prevent sticking. Begin layering by spreading half of the beef and pasta mixture into the dish. Then, drop spoonfuls of the ricotta mixture evenly on top. Carefully cover with the remaining beef and pasta, spreading it out evenly using the back of a spoon. This no-fuss layering gives you all the lasagna flavor without fiddly sheets of noodles.

Step 5: Bake and Finish

Cover the casserole with foil and bake for 30 minutes to heat through and meld the layers. Then, remove the foil and sprinkle remaining mozzarella and Parmesan cheeses on top. Return to the oven uncovered for another 5 to 10 minutes or until the cheese is melted, bubbly, and lightly golden. Finally, let the casserole rest for about 5 minutes before serving to set everything up nicely. Garnish with fresh basil if you like—this final touch adds bright freshness and gorgeous color to your Lazy Lasagna Casserole Recipe.

Garnishes

A sprinkle of fresh basil leaves or a few extra parsley flakes add a lovely burst of color and a touch of fresh herbal flavor that contrast beautifully with the rich, cheesy layers.

Side Dishes

This casserole is hearty and satisfying on its own, but pairing it with a crisp green salad drizzled with vinaigrette or a simple garlic bread makes a well-rounded, comforting meal that everyone will love.

Creative Ways to Present

Try serving the Lazy Lasagna Casserole Recipe in individual ramekins for personal portions, or layer it in a deep skillet for a rustic, family-style presentation. Either way, the gooey cheese and rich sauce shine through and create a beautiful centerpiece.

Make Ahead and Storage

Storing Leftovers

After enjoying your Lazy Lasagna Casserole Recipe, store any leftovers in an airtight container in the refrigerator. They will keep well for up to 3 days, and the flavors often intensify overnight, making for an even tastier next meal.

Freezing

If you want to save some for later, this casserole freezes beautifully! Assemble it in a freezer-safe dish, cover tightly, and freeze for up to 3 months. When ready to eat, thaw overnight in the fridge before baking.

Reheating

Reheat leftovers in the oven at 350°F, covered with foil, until heated through and bubbly (about 20 minutes). You can also microwave individual portions, but reheating in the oven keeps the texture and flavors more vibrant.

FAQs

Can I use a different type of pasta in this Lazy Lasagna Casserole Recipe?

Absolutely! Campanelle works great, but short pastas like penne, ziti, or medium shells will also hold the sauce well and make a delicious casserole.

Is it possible to make this recipe vegetarian?

Yes, you can skip the ground beef and substitute with sautéed mushrooms, lentils, or a plant-based meat alternative to keep the hearty texture and flavor.

Can I prepare this casserole in advance?

Definitely. You can assemble the casserole ahead of time, cover it, and refrigerate for up to 24 hours before baking. Just add an extra 5-10 minutes to the baking time if baking straight from the fridge.

What’s the best way to get a bubbly cheese topping?

Make sure to remove the foil during the last 5 to 10 minutes of baking so the mozzarella and Parmesan can melt and brown slightly, giving that perfect cheesy crust.

Can I use full-fat cheeses instead of part-skim?

Yes, full-fat ricotta and mozzarella will make the casserole even richer and creamier, but part-skim works great for a lighter option without sacrificing too much flavor.

Final Thoughts

This Lazy Lasagna Casserole Recipe is a total game-changer for lasagna lovers who want all the comfort and taste without the lengthy prep time. It’s simple, satisfying, and delivers all the cheesy, savory goodness you crave. I encourage you to give it a try the next time you want a fuss-free dinner that feels special and homemade. It’s sure to become a fast favorite in your recipe rotation!

Description

This Lazy Lasagna Casserole is a quick and easy twist on traditional lasagna, combining cooked pasta, seasoned ground beef, and a creamy ricotta cheese layer baked to bubbly perfection. Perfect for a comforting family meal that requires minimal effort and maximum flavor.


Ingredients

Pasta

  • 10 ounces campanelle (or another short pasta like penne, ziti, or medium shells)

Meat Sauce

  • 1 pound lean ground beef
  • ½ cup diced onion
  • ½ teaspoon minced garlic (divided)
  • 1 teaspoon Italian Seasoning
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 25 ounces marinara sauce (preferably Mezzetta's Marinara)
  • ¼ cup water

Cheese Mixture

  • 1 cup part-skim ricotta cheese
  • 1 egg
  • 3 cups shredded part-skim mozzarella cheese (divided)
  • ½ cup grated Parmesan cheese (divided)
  • ½ teaspoon minced garlic (remaining)
  • 1 teaspoon dried parsley flakes (or 1 tablespoon fresh)
  • ¼ teaspoon black pepper (remaining)

Garnish

  • Fresh basil (optional)


Instructions

  1. Cook Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook it for one minute less than the package directions indicate. Drain the pasta well and set it aside to prevent overcooking during baking.
  2. Prepare Meat Sauce: In a large deep skillet or Dutch oven, heat over medium. Add ground beef, diced onion, and half of the minced garlic. Cook until the beef is no longer pink and onions are softened. Drain excess grease and return the pan to heat. Season with Italian Seasoning, salt, and a quarter teaspoon of black pepper. Stir for a minute or two to combine the flavors. Add marinara sauce and water, simmer gently for a few minutes until warmed through. Stir in the cooked pasta, then remove from heat and set aside.
  3. Preheat Oven and Prepare Dish: Preheat your oven to 350°F (175°C). Lightly coat a 13- x 9-inch baking dish with non-stick cooking spray to prevent sticking.
  4. Mix Cheese Filling: In a large mixing bowl, combine ricotta cheese and egg until smooth. Stir in half of the shredded mozzarella, remaining minced garlic, half of the Parmesan cheese, dried parsley flakes, and remaining black pepper. Mix well to create a creamy cheese layer.
  5. Layer Casserole: Spread half of the beef and pasta mixture evenly in the prepared baking dish. Spoon dollops of the ricotta cheese mixture over the meat layer, distributing evenly. Carefully top with the remaining beef and pasta mixture, spreading it gently with the back of a spoon to cover the cheese layer completely.
  6. Bake Covered: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 30 minutes. This allows the casserole to heat evenly and the flavors to meld.
  7. Add Cheese Topping and Bake Uncovered: Remove the foil and sprinkle the remaining mozzarella and Parmesan cheeses evenly over the top. Return to the oven and bake uncovered for an additional 5 to 10 minutes or until the casserole is bubbly and the cheese is melted and lightly golden.
  8. Serve: Garnish with fresh basil leaves if desired. Let the casserole rest for 5 minutes before serving to allow it to set and make serving easier.

Notes

  • You can substitute campanelle with penne, ziti, or medium shell pasta as preferred.
  • For a richer flavor, use full-fat cheeses instead of part-skim, but this will increase calories and fat content.
  • Make sure not to overcook the pasta during boiling to prevent mushy texture after baking.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • Adding fresh basil as a garnish adds a bright herbal note, but it is optional.
