What You Need

  • 1/4 cup whole-milk cottage cheese
  • 1 cup grated Parmesan cheese
  • 1/2 teaspoon granulated garlic
  • Sea salt and pepper
  • 1 pound hot or sweet Italian sausage, casings removed, crumbled into 1/2-inch pieces
  • 10 ounces cremini mushrooms, trimmed and sliced thin
  • 4 cups baby spinach
  • 1 (24-ounce) jar marinara sauce
  • 6 no-boil lasagna noodles
  • 2 cups shredded whole-milk mozzarella cheese

Mix the Cheese

Heat oven to 425F with rack in the middle.

Mix cottage cheese, Parmesan, garlic, and 1/4 teaspoon pepper in a bowl.

Microwave the Filling

Put sausage, mushrooms, 1/4 teaspoon salt, and 1/4 teaspoon pepper in a microwave-safe bowl.

Cover and microwave ~9 minutes, stirring every few minutes. The sausage should lose its pink and mushrooms release liquid.

Add spinach, microwave 1 more minute until wilted. Drain in a colander 5 minutes. Press with a spoon to squeeze out liquid – this step matters or you’ll get watery lasagna.

Layer It Up

Grease an 8-inch square baking dish. Spread 1 cup marinara on bottom. Lay 2 noodles (they’ll overlap).

Add half the sausage mixture, half the cheese mixture, 1/2 cup mozzarella.

Repeat: 2 noodles, 1 cup marinara, remaining sausage, remaining cheese mixture, 1/2 cup mozzarella.

Top with last 2 noodles, remaining marinara, and final cup mozzarella.

Bake

Cover tight with greased foil. Bake ~30 minutes until edges bubble.

Remove foil, bake 10-15 minutes more until cheese browns. Rotate dish halfway through.

Rest 15 minutes before cutting.

Whole-milk cottage cheese works best – low-fat is OK but skip nonfat. Victoria marinara has the right consistency. Make ahead and refrigerate up to 24 hours – just bake covered for 45 minutes instead.
