Step‑by‑Step Instructions for Hearty Vegetarian Southern Casserole

Step 1: Prep Ingredients
Begin by washing and chopping your mixed vegetables, such as bell peppers, zucchini, and carrots, into uniform pieces. Next, drain and rinse the canned beans to remove excess sodium. This ensures a fresh taste and texture in your Hearty Vegetarian Southern Casserole as you prepare for the next steps.

Step 2: Sauté Aromatics
Set your Instant Pot to the sauté function and allow it to heat up. Add a splash of olive oil, then toss in finely chopped onions and minced garlic. Sauté for about 3-5 minutes until the onions become translucent and fragrant. This step builds a flavorful base for your casserole, setting a delicious tone for the dish.

Step 3: Combine and Cook
Add the chopped mixed vegetables, canned diced tomatoes, and vegetable broth into the pot. Sprinkle in your herbs and spices—like oregano, basil, salt, and pepper—then stir well to combine all the ingredients. Cook on the sauté setting for an additional 3-4 minutes, allowing the vegetables to soften slightly while mingling their flavors.

Step 4: Add Protein
Incorporate the drained beans into the mixture, ensuring they are evenly distributed throughout the vegetable medley. If you prefer a firmer texture, you can substitute with cubed tofu or tempeh. Stir until every ingredient is well combined, filling your kitchen with the inviting aroma of your Hearty Vegetarian Southern Casserole.

Step 5: Pressure Cook
Seal the Instant Pot lid securely, ensuring the vent is closed. Set it to cook on high pressure for 10 minutes. Once the timer goes off, allow for a natural release of pressure for 5 minutes before performing a manual release. This gentle cooking method ensures tender vegetables and deeply developed flavors in your casserole.

Step 6: Top and Broil
After releasing pressure, open the Instant Pot and stir in shredded cheese and breadcrumbs to create a golden topping. Transfer the mixture into a baking dish and switch your oven to the broil setting. Broil for 3-5 minutes or until the cheese is bubbly and golden brown, creating that delightful contrast to the creamy base of your Hearty Vegetarian Southern Casserole.

Make Ahead Options

These Hearty Vegetarian Southern Casserole preparations are ideal for busy cooks looking to save time during hectic weeknights! You can chop and sauté the mixed vegetables up to 24 hours in advance, allowing for easy assembly later; simply refrigerate them in an airtight container. Additionally, the entire casserole can be prepared ahead and stored in the fridge for up to 3 days before cooking. To maintain flavor and texture, make sure to cover it tightly.

Seasonal veggies are a fantastic choice, as they often have superior flavor and nutrition.

What’s the best way to store leftovers from the casserole?
You can store your Hearty Vegetarian Southern Casserole in an airtight container in the fridge for up to 3 days. Let it cool completely before sealing to maintain its delicious flavors. For optimal freshness, place parchment paper between the casserole and the lid to avoid moisture buildup.

What should I do if my casserole is too watery?
If your casserole turns out too watery, don’t worry! You can thicken it up. First, let it simmer uncovered on the sauté setting of the Instant Pot for a few minutes to evaporate excess liquid.
