Step‑by‑Step Instructions for Easy Low-Carb Vegetarian Casserole for the Instant Pot
Step 1: Prep the Vegetables
Begin by washing and chopping the mixed bell peppers, zucchini, and mushrooms into bite-sized pieces. Aim for uniform sizes to ensure even cooking. Set your Instant Pot to the side, as setting up your ingredients now will streamline the cooking process later.
Step 2: Sauté
Select the sauté function on your Instant Pot and pour in a drizzle of olive oil. Once the oil shimmers, add your chopped vegetables and sauté them for about 5-7 minutes. Stir occasionally until they become soft and slightly golden. The lovely aroma will fill your kitchen, setting the stage for the Easy Low-Carb Vegetarian Casserole.
Step 3: Mix Ingredients
In a large mixing bowl, whisk together the eggs, vegetable broth, cheese, and fresh herbs. Once well combined, gently fold in the sautéed vegetables from the Instant Pot, ensuring everything is evenly distributed. The mixture should be moist and vibrant, ready to be transformed into a hearty casserole.
Step 4: Pressure Cooking
Carefully pour the vegetable mixture back into the Instant Pot, spreading it evenly. Close the lid securely and set the pressure release valve to sealing. Choose the manual high pressure setting and cook for 10 minutes, allowing the flavors to meld and the dish to set perfectly.
Step 5: Release Pressure
Once the cooking time is complete, use a quick release to release the pressure, carefully turning the valve to venting. Wait for the steam to dissipate before opening the lid. The casserole should look puffy and slightly golden, signaling that it’s ready to be enjoyed.
Step 6: Serve
Allow the Easy Low-Carb Vegetarian Casserole to cool for a few minutes in the pot before slicing it into squares for easy serving. The interior should be creamy and rich, reminiscent of a comforting quiche. Pair it with a fresh green salad or crusty whole-grain bread for a wholesome meal!
