Step‑by‑Step Instructions for Southern Vegetarian Casserole

Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). This ensures a perfectly cooked Southern Vegetarian Casserole as soon as it’s ready to bake. While the oven heats, gather your ingredients so they’re easily accessible, making the prep work seamless.

Step 2: Sauté Vegetables
In a large skillet over medium heat, add a drizzle of olive oil and sauté diced onions and bell peppers for about 5 minutes, stirring frequently until they soften and turn translucent. The delightful aroma will fill your kitchen, setting the stage for the rich flavors of your casserole.

Step 3: Add Zucchini
Next, mix in the chopped zucchini and continue to cook for an additional 3-4 minutes. You want the zucchini to be slightly tender but still retain some bite. Stir occasionally to ensure even cooking, allowing the veggies to meld their flavors together beautifully.

Step 4: Incorporate Sauce and Seasonings
Pour in the tomato sauce and sprinkle your preferred spices, such as garlic powder and Italian seasoning, into the skillet. Stir everything together until well combined, allowing the sauce to coat all the vegetables. Let it cook for an extra 2 minutes for the flavors to develop.

Step 5: Mix in Cheese and Eggs
In a separate bowl, whisk the eggs thoroughly before folding them into the vegetable mixture. Then, sprinkle in your choice of cheese, mixing until everything is well integrated. The eggs and cheese work together to bind the casserole, creating a rich, satisfying texture.

Step 6: Transfer to Baking Dish
Lightly grease a baking dish with olive oil, then pour the vegetable mixture into the dish. Spread it evenly across the surface to ensure uniform baking. This way, every slice of your Southern Vegetarian Casserole will boast a perfect blend of textures and flavors.

Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 25-30 minutes. You’re looking for the casserole to be set in the center and golden brown on top, creating a bubbly, inviting crust that beckons you to dig in.

Step 8: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for about 5-10 minutes before slicing. This resting time helps the layers firm up a bit, making it easier to portion. Serve warm, and enjoy the comforting flavors of your homemade Southern Vegetarian Casserole!
