Ingredients for Lazy Lasagna Casserole

The Pasta and Meat Sauce

2 cups uncooked penne pasta (200 g)
1 tbsp olive oil (15 ml)
1 lb lean ground beef (450 g)
1 large yellow onion, chopped (150 g)
1 tbsp garlic powder (15 g)
2 tsp Italian seasoning (10 g)
Salt to taste
Black pepper to taste (5 g)
1 cup cottage cheese (240 g)
24 oz jar of pasta sauce (680 g)

The Cheese Topping

8 oz mozzarella cheese, shredded (225 g)
Fresh basil, chopped for garnish (10 g)

Ingredient Notes

If you’d like to make this casserole more nutritious, use whole wheat pasta or add finely chopped spinach to the sauce. For extra flavor, try blending a bit of ricotta with the cottage cheese for a creamier texture. You can also use light mozzarella for a slightly lower-fat version without sacrificing taste.

How to Make Lazy Lasagna Casserole

Step 1 – Cook the Pasta

Preheat your oven to 350°F (175°C) and grease a 9×13-inch casserole dish. Bring a pot of salted water to a boil and cook the penne one minute less than package directions for that perfect al dente texture. Drain and set aside.

Step 2 – Prepare the Meat Sauce

In a large skillet over medium-high heat, warm the olive oil. Add the ground beef, chopped onion, garlic powder, Italian seasoning, salt, and black pepper. Stir and break up the meat as it cooks for about 7 to 8 minutes until browned and fragrant.

Step 3 – Combine the Mixture

Reduce heat to medium. Stir in the cottage cheese until well blended, then pour in the pasta sauce. Add the cooked pasta and stir gently until everything is evenly coated and deliciously saucy.

Step 4 – Bake It

Transfer the mixture into the greased dish and spread it evenly. Sprinkle mozzarella cheese over the top. Bake for 15 minutes until the cheese is bubbly and golden on the edges.

Step 5 – Serve and Garnish

Remove from the oven, let it rest for a few minutes, and top with freshly chopped basil. Slice into hearty portions and serve warm.

Pro Tips for Success

• Always undercook the pasta slightly since it continues cooking in the oven.
• Use freshly shredded mozzarella for the best melt.
• Don’t skip resting time; it helps the casserole set perfectly.
• Taste your sauce before baking to adjust seasoning.
• Freeze portions individually for quick, ready-to-go meals.
• Add a touch of red pepper flakes if you enjoy a mild kick.

Flavor Variations

• Swap penne for rotini or rigatoni for a twist on texture.
• Add diced zucchini or mushrooms for extra veggies.
• Stir in a handful of spinach for color and nutrition.
• Mix cottage cheese with a spoon of cream cheese for a richer layer.
• Sprinkle parmesan on top before baking for more flavor depth.

Serving Suggestions

Serve your Lazy Lasagna Casserole with a crisp side salad and warm garlic bread for the ultimate cozy dinner. A bowl of Classic Minestrone Soup also pairs beautifully, turning this dish into a comforting Italian-inspired feast.

For something lighter, try steamed green beans or roasted broccoli drizzled with olive oil and a pinch of sea salt.

Storage and Freezing Instructions

Store leftovers in an airtight container in the refrigerator for up to four days. To reheat, warm in the oven at 325°F until heated through or microwave in short intervals.

For freezing, let the casserole cool completely, then wrap portions tightly. It keeps well in the freezer for up to two months. Thaw overnight in the refrigerator and reheat gently.
