Step‑by‑Step Instructions for Hearty Low-Carb Vegetarian Casserole
Step 1: Preheat and Prepare
Start by turning your Instant Pot to the sauté mode and add a tablespoon of olive oil. Allow the oil to heat up for about 1-2 minutes until it shimmers. This will create a flavorful base for your Hearty Low-Carb Vegetarian Casserole, making sure that every ingredient is coated in that delicious oil.
Step 2: Sauté Aromatics
Add the chopped onions and minced garlic to the hot olive oil. Sauté them for 2-3 minutes, stirring frequently, until the onions become translucent and fragrant. Ensure not to let the garlic burn as this can alter the flavor. This step sets the foundation for an aromatic, comforting casserole.
Step 3: Add Vegetables
Next, incorporate the diced zucchini, bell peppers, and chopped spinach into the pot. Stir gently, cooking for approximately 5 minutes until the vegetables are just beginning to soften but still retain a bit of crunch. This bright medley not only adds color but also layers of flavor to your low-carb casserole.
Step 4: Mix in Cheese and Herbs
Stir in your choice of dried herbs like Italian seasoning and sprinkle in the cheese for that creamy texture. Mix everything well, letting the cheese melt slightly as you combine the ingredients. The mixture should be warm and comforting, a sign that your Hearty Low-Carb Vegetarian Casserole is nearing completion.
Step 5: Pressure Cook
Secure the Instant Pot lid firmly in place, ensuring the valve is set to sealing. Set it to manual high pressure and cook for 5 minutes. Listen for the pot to come to pressure and keep an eye on the timer. This quick cooking method brings everything together while maintaining the freshness of your veggies.
Step 6: Release and Serve
Once the cooking time is complete, carefully perform a quick-release of the pressure. Allow the steam to escape until the pin drops, then open the lid. Let your Hearty Low-Carb Vegetarian Casserole cool slightly before serving. Enjoy this comforting dish alongside a fresh salad or crusty bread for a complete meal.
