Ingredients
Scale
- 3 medium zucchinis, sliced into half-moons or rounds (about 1/4 inch thick)
- 1 pound Italian sausage (bulk or casings removed), mild or spicy
- 1 1/2 cups shredded mozzarella cheese (about 150g)
- 1/2 cup shredded Parmesan cheese (about 50g)
- 2 tablespoons extra virgin olive oil
- 3 cloves garlic, minced
- 1 teaspoon dried Italian herbs (basil, oregano, thyme blend)
- Pinch of red pepper flakes (optional)
- Salt to taste (about 1 teaspoon)
- Black pepper to taste (about 1/2 teaspoon)
- Fresh parsley, chopped for garnish (optional)
Instructions
- Preheat your oven to 425°F (220°C) and set the rack in the middle position.
- Wash and dry the zucchinis well. Slice into half-moons roughly 1/4 inch thick.
- Remove casing from sausage if needed and crumble into a skillet over medium heat. Cook for 3-4 minutes until slightly browned but not fully cooked.
- In a large mixing bowl, toss zucchini slices, browned sausage, minced garlic, olive oil, dried Italian herbs, red pepper flakes (if using), salt, and pepper until evenly coated.
- Spread the mixture in a single layer on a prepared half-sheet pan (18×13 inches). Avoid overcrowding to prevent steaming.
- Roast uncovered for 15 minutes. Stir or shake the pan to flip zucchini and sausage pieces for even cooking.
- Sprinkle mozzarella and Parmesan cheese evenly over the top.
- Return to the oven and roast for another 10-12 minutes until cheese is bubbly and golden brown.
- Check that zucchini is tender but still firm and sausage is fully cooked (internal temp 160°F). Broil for 1-2 minutes if cheese needs more browning, watching closely.
- Garnish with chopped fresh parsley before serving.
Notes
Pat zucchini slices dry with paper towels if they release a lot of water to avoid sogginess. Do not overcrowd the pan to ensure roasting instead of steaming. Browning sausage before roasting helps render fat and prevents greasiness. Check casserole around 25 minutes to avoid mushy zucchini. Can broil briefly for extra cheese browning.
