Cook Time 35 minutes
Total Time 50 minutes
Servings: 6 servings

Ingredients
  

  • Italian sausage: 1 to 1.25 pounds, casings removed (mild or hot, your choice).
  • Zucchini: 3 medium, sliced into 1/4-inch rounds or half-moons.
  • Yellow onion: 1 medium, thinly sliced.
  • Garlic: 3 to 4 cloves, minced.
  • Crushed tomatoes or marinara sauce: 2 cups (about 16 ounces). Use a quality brand.
  • Tomato paste: 1 tablespoon, for a richer sauce.
  • Olive oil: 1 to 2 tablespoons, for sautéing.
  • Italian seasoning: 1 teaspoon (or a mix of dried oregano and basil).
  • Red pepper flakes: 1/4 teaspoon, optional for heat.
  • Salt and black pepper: To taste.
  • Mozzarella cheese: 1 1/2 cups shredded.
  • Parmesan cheese: 1/3 cup grated.
  • Fresh basil or parsley: A handful, chopped, for garnish.
  • Optional add-ins: Sliced bell pepper, baby spinach, mushrooms, or a splash of red wine.

Method
 

  1. Prep the oven and pan: Heat the oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish or similar.
  2. Brown the sausage: Warm a large skillet over medium-high heat. Add olive oil and the sausage. Break it up with a spoon and cook until browned and no longer pink, about 6 to 8 minutes. Spoon off excess fat if needed.
  3. Add aromatics: Stir in the onion and cook until softened, 3 to 4 minutes. Add garlic and cook 30 to 60 seconds until fragrant.
  4. Build the sauce: Stir in crushed tomatoes (or marinara), tomato paste, Italian seasoning, red pepper flakes, and a pinch of salt and pepper. If using, add a splash of red wine. Simmer 3 to 5 minutes to thicken slightly. Taste and adjust seasoning.
  5. Season the zucchini: In a bowl, toss zucchini with a drizzle of olive oil, a pinch of salt, and pepper. This helps it roast rather than steam.
  6. Layer the bake: Spread a thin layer of sauce in the baking dish. Add half the zucchini in an even layer, then spoon over half the remaining sauce and sprinkle with one-third of the mozzarella. Repeat with the remaining zucchini and sauce, then top with the rest of the mozzarella and all the Parmesan.
  7. Bake: Cover loosely with foil and bake for 15 minutes. Remove the foil and bake another 10 to 15 minutes, until the cheese is bubbling and lightly golden and the zucchini is tender.
  8. Rest and finish: Let the bake rest for 5 to 10 minutes so it sets. Sprinkle with chopped basil or parsley before serving.
  9. Serve: Spoon into bowls and pair with garlic bread, a green salad, or cooked pasta if you want something heartier.
