Step‑by‑Step Instructions for Easy Vegetarian Southern Casserole
Step 1: Preheat and Prepare
Begin by preheating your Instant Pot using the sauté function. Once hot, add a drizzle of olive oil, enough to coat the bottom. Dice your bell peppers and zucchini, then toss them into the pot. Sauté the vegetables for about 5 minutes, stirring occasionally until they are slightly softened and vibrant.
Step 2: Build the Creamy Base
Next, stir in the cream of mushroom soup and your choice of shredded cheddar or mozzarella cheese. Mix thoroughly until the cheese is melted and everything is well-combined. This creamy mixture should be smooth and inviting, enveloping the sautéed veggies in deliciousness, setting the stage for the casserole.
Step 3: Add the Grains and Seasoning
Now, add in your choice of couscous or quinoa, ensuring it gets evenly distributed throughout the creamy mixture. Sprinkle in salt, pepper, garlic powder, and onion powder to taste. Carefully fold everything together, but avoid overmixing, as this will keep your grains fluffy and delicious in the finished casserole.
Step 4: Seal and Cook
Once all ingredients are combined, secure the lid of the Instant Pot, ensuring it’s locked in place. Set the valve to the sealing position and select high pressure. Cook for 10 minutes. During this time, your kitchen will fill with fragrant aromas from this Easy Vegetarian Southern Casserole.
Step 5: Quick Release and Serve
After the cooking time is up, perform a quick release by carefully turning the valve to venting to release any remaining steam. Once the steam is completely released, carefully open the lid. Give the casserole a gentle stir to incorporate everything again before serving it hot, perfect for every gathering.
How to Store and Freeze Vegetarian Casserole
Fridge: Store leftovers in an airtight container in the fridge for up to 3 days. This ensures your delicious vegetarian casserole stays fresh while you’re enjoying it throughout the week.
Freezer: For longer storage, freeze the casserole in a tightly sealed container for up to 3 months. This is perfect for preparing meals in advance or saving portions for later enjoyment.
Reheating: When ready to enjoy, reheat in the microwave or oven. If reheating in the oven, add a splash of water to keep it moist. Enjoy that comforting taste again!
Making Ahead: You can also make the casserole ahead of time and refrigerate it before cooking. Just remember to adjust the cooking time if it’s chilled!
Expert Tips for the Best Vegetarian Casserole
• Evenly Diced Vegetables: Ensure vegetables are chopped uniformly, which promotes even cooking and texture throughout your dish.
• Grease the Pot: Lightly grease the Instant Pot before adding ingredients to prevent sticking and make cleanup a breeze.
• Gentle Mixing: Avoid overmixing after adding the grain; this keeps the casserole fluffy and allows the couscous or quinoa to shine.
• Cooking Variations: If opting for brown rice, remember that it requires a longer cooking time of about 22 minutes, not the standard 10.
