Step‑by‑Step Instructions for Vegetarian Southern-Inspired Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This step ensures that your Vegetarian Southern-Inspired Casserole bakes evenly and achieves a golden, bubbly top. Preheating typically takes about 10–15 minutes, giving you a chance to prepare your ingredients while the oven warms up.
Step 2: Chop the Vegetables
While the oven heats, chop your cauliflower, bell peppers, and onion into bite-sized pieces. Aim for uniform sizes to ensure even cooking. Spread out your chopped veggies on a cutting board, and enjoy the vibrant colors as they come together; they will be the base of your hearty casserole.
Step 3: Sauté Garlic and Onion
In an Instant Pot or skillet, add a splash of olive oil and sauté the chopped onion and minced garlic together over medium heat for about 3–5 minutes. Stir occasionally until the onion becomes fragrant and translucent, filling your kitchen with a warm aroma. This step enhances the flavor base for your casserole.
Step 4: Add Cauliflower and Bell Peppers
Next, incorporate the chopped cauliflower and bell peppers into the pot. Stir the mixture well and let them sauté for an additional 5–7 minutes. You want the vegetables to soften slightly while still maintaining their shape, providing the perfect texture for your Vegetarian Southern-Inspired Casserole.
Step 5: Pour in the Vegetable Broth
Pour the vegetable broth into the pot, ensuring all the vegetables are submerged. Allow the mixture to simmer for about 10 minutes, until the cauliflower and bell peppers are tender. You’ll know it’s ready when the veggies are just soft enough to pierce with a fork, but still preserve their vibrant color.
Step 6: Melt in the Cream Cheese
Carefully stir in the cream cheese, mixing thoroughly until it melts and integrates into the mixture. This step will create a rich, creamy sauce that binds all the flavors together. If you prefer a lighter option, you can substitute the cream cheese with Greek yogurt for a savory twist.
Step 7: Transfer to Baking Dish
Once the mixture is well combined and creamy, transfer it to a greased baking dish. Even it out with a spatula to ensure even cooking. This layer of comfort will serve as the hearty foundation of your casserole, ready to soak up the delicious flavors from the oven.
Step 8: Add the Cheddar Cheese
Sprinkle a generous layer of cheddar cheese over the top of the casserole. This will create a deliciously melty and gooey topping that contrasts beautifully with the creamy mixture below. Feel free to experiment with different cheeses or even vegan options if you prefer.
Step 9: Bake Until Bubbly
Place the baking dish in the preheated oven and bake for 20-25 minutes. Keep an eye out for a bubbly, golden top that indicates the casserole is ready. The aroma filling your kitchen will signal that comfort food is just moments away from being served.
Step 10: Let it Rest and Serve
After removing the casserole from the oven, let it rest for about 5 minutes to set. This slight cooling period allows flavors to meld together beautifully. Serve your Vegetarian Southern-Inspired Casserole warm and enjoy the comforting, creamy goodness with family and friends!

Make Ahead Options
These Vegetarian Southern-Inspired Casseroles are ideal for meal prep, allowing you to savor their comforting flavors on busy weeknights!
