How to Make Low Carb Zucchini and Sausage Casserole
Prepare the Zucchini: Begin by slicing the zucchinis into thin rounds. These will cook beautifully and create the perfect base for your casserole. Set them aside while you start on the sausage.
Cook the Sausage: In a large skillet over medium heat, crumble the Italian sausage. Cook until browned and fully cooked through, about 5-7 minutes. The sizzling aroma will fill your kitchen with deliciousness!
Add Tomatoes and Seasoning: Stir in the diced tomatoes and Italian seasoning with the sausage. Allow this mixture to simmer for about 3-4 minutes, so the flavors can mingle together in a delightful embrace.
Layer the Casserole: Preheat your oven to 375 °F (190 °C). In a baking dish, layer half of the zucchini slices at the bottom. Spoon half of the sausage mixture over the zucchini, then sprinkle half of the mozzarella cheese on top. Repeat the layers, finishing with the remaining mozzarella.
Bake to Perfection: Pop the casserole into the preheated oven and bake for 25-30 minutes. It s done when the cheese is bubbly and slightly golden, and the zucchini is tender yet still has a little bite.
Garnish and Serve: Once out of the oven, let it cool for a few minutes. Sprinkle fresh basil on top for a burst of color and flavor before serving.
Optional: Serve with a side salad for a refreshing complement!
