Step‑by‑Step Instructions for Creamy Vegetarian Casserole
Step 1: Sauté Vegetables
In your Instant Pot, select the sauté function and heat a splash of olive oil. Add chopped bell peppers, mushrooms, and diced onions, stirring frequently for about 5–7 minutes until they soften and become fragrant. The vegetables should turn tender but still retain some crunch, creating a colorful foundation for your creamy vegetarian casserole.
Step 2: Add Spinach
Next, stir in the fresh or frozen spinach and allow it to wilt, which should take about 2–3 minutes. You’ll notice the vibrant green color deepening as the spinach cooks down, seamlessly incorporating into the sautéed vegetables. This step enhances both the nutrition and flavor of your casserole.
Step 3: Mix Cream Mixture
While the vegetables are cooking, take a mixing bowl and combine softened cream cheese with vegetable broth until smooth. Using a whisk or fork, blend in the Italian seasoning, ensuring even distribution of flavors. The mixture should be creamy and easily pourable, ready to enhance the vegetable medley in your casserole.
Step 4: Combine
Pour the cream mixture over the sautéed vegetables in the Instant Pot. Gently stir everything together until the vegetables are well-coated in the creamy goodness. This will create a rich flavor base for your creamy vegetarian casserole, with all ingredients melding beautifully.
Step 5: Pressure Cook
Seal the Instant Pot lid and set it to cook on high pressure for 10 minutes. The pot will take a few minutes to come to pressure, indicated by a silent pause before it starts the countdown. Once the time is up, you’ll hear a beep, and the aroma of your savory casserole will fill the kitchen.
Step 6: Release Pressure
Carefully perform a quick release on the Instant Pot, allowing steam to escape fully before opening the lid. Gently stir the casserole to redistribute the flavors, and then add the shredded cheddar cheese. The heat will melt the cheese perfectly, creating an irresistible gooey topping for your casserole.
Step 7: Serve
Spoon the creamy vegetarian casserole into serving bowls, garnishing with fresh herbs like parsley or basil for an extra pop of color and flavor. Serve warm, perhaps alongside a vibrant side salad or whole-grain bread, to complement this comforting dish and delight your family and friends.
