Step‑by‑Step Instructions for Easy Vegetarian Southern Casserole in the Instant Pot

Step 1: Prep Vegetables
Begin by washing and chopping the zucchini, bell peppers, and onion into bite-sized pieces, making sure they are uniform for even cooking. This vibrant mix will form the base of your Easy Vegetarian Southern Casserole. Set them aside so they are ready for the next step of the cooking process.

Step 2: Sauté Onion
In your Instant Pot, select the sauté function and heat a splash of oil over medium heat. Add the chopped onion and sauté for about 3-4 minutes, or until the onion turns translucent and fragrant. This will provide a flavorful foundation for your casserole and should be watched to avoid burning.

Step 3: Combine Ingredients
Once the onion is ready, add the chopped zucchini, bell peppers, and corn to the pot. Pour in the vegetable broth and sprinkle in the garlic powder, salt, and pepper. Stir everything together for 2-3 minutes until well combined, ensuring that the vegetables begin to soften and blend with the broth.

Step 4: Add Cream Cheese
Cube the cream cheese and distribute the pieces evenly on top of the vegetable mixture. This step is crucial for achieving that creamy texture in your Easy Vegetarian Southern Casserole. Allow it to sit for a minute or two to soften slightly before proceeding to the next step.

Step 5: Pressure Cook
Seal the Instant Pot lid securely and ensure the valve is set to the sealing position. Set it to high pressure for 10 minutes. While it cooks, you can look forward to the rich aromas that will be filling your kitchen, offering a preview of the delicious meal to come.

Step 6: Release Pressure
Once the cooking time is complete, allow the Instant Pot to naturally release pressure for about 5-10 minutes. After this, carefully switch the valve to venting to release any remaining steam. Open the lid, and you’ll be greeted by a wonderfully aromatic Easy Vegetarian Southern Casserole.

Step 7: Stir in Cheese
Stir in your choice of shredded cheese until it melts into the casserole, creating a delightful creamy layer. You can use cheddar or mozzarella, depending on your preference. This step is vital to enhancing the flavor and bringing everything together.

Step 8: Add Topping (Optional)
If you desire a crispy finish, sprinkle breadcrumbs on top of your casserole. For an extra touch, you can place the pot under the broiler for a few minutes to achieve a golden brown crust. Keep a close eye on it to prevent burning.

Step 9: Serve and Enjoy
Finally, spoon the Easy Vegetarian Southern Casserole into bowls while it’s warm, ready to serve to your family or guests. Its creamy consistency and vibrant veggies ensure every bite is satisfying. Pair it with a fresh salad or crusty bread for a complete, delightful meal!

Make Ahead Options

Busy home cooks will love how easy it is to prepare the Easy Vegetarian Southern Casserole ahead of time! You can chop the zucchini, bell peppers, and onion and refrigerate them up to 24 hours in advance to save on prep time. Additionally, you can assemble the entire casserole and store it in the fridge for up to 3 days before cooking; just cover it tightly with plastic wrap or foil. To maintain quality, ensure the cream cheese is softened before adding it to prevent clumping. When ready to serve, simply pressure cook as directed, and enjoy a delicious, homemade meal with minimal last-minute effort!
