Step‑by‑Step Instructions for Low-Carb Vegetarian Southern Casserole Step 1: Preheat the Oven Start by preheating your oven to 375°F (190°C). This ensures that your Low-Carb Vegetarian Southern Casserole will bake evenly, achieving that delightful golden top. While the oven warms up, gather and prepare your ingredients for a smooth cooking experience. Step 2: Sauté the Vegetables In a large skillet, heat a splash of olive oil over medium heat. Add the chopped zucchini, diced bell peppers, and sliced mushrooms, sautéing for about 5-7 minutes until they are softened and fragrant. You’ll know they’re ready when the vegetables are tender and slightly caramelized, locking in those rich flavors that will enhance your casserole. Step 3: Add the Spinach Stir in the fresh or well-drained frozen spinach into the sautéed vegetables. Cook for an additional 2-3 minutes until the spinach is wilted and vibrant. Season your mixture with salt and pepper for added flavor, elevating this Low-Carb Vegetarian Southern Casserole to new heights of deliciousness. Step 4: Mix the Casserole Base In a large mixing bowl, combine the creamy ricotta cheese, beaten eggs, Italian seasoning, and almond flour. Use a fork or whisk to blend these ingredients until smooth and uniform. This mixture acts as the glue for your casserole, binding the vegetables and giving it a rich texture, perfect for a comforting family meal. Step 5: Combine All Ingredients Fold the sautéed vegetable mixture into the ricotta mixture, ensuring every piece of vegetable is evenly coated. This step is essential for integrating all the flavors into your Low-Carb Vegetarian Southern Casserole, making each bite satisfyingly delicious. Step 6: Assemble the Casserole Pour the combined mixture into a greased baking dish, spreading it evenly. To add a lovely melty topping, generously sprinkle shredded mozzarella cheese over the top of the casserole. This not only enhances the presentation but also creates a gooey layer that everyone will love. Step 7: Bake to Perfection Place the baking dish in your preheated oven and bake for 30-35 minutes.
