Step‑by‑Step Instructions for Easy Vegetarian Low-Carb Casserole

Step 1: Prepare Ingredients
Begin by thoroughly washing and chopping your zucchini and bell peppers into bite-sized pieces. Rinse the spinach and set it aside to drain. If using fresh cauliflower, cut it into florets and pulse in a food processor until it resembles rice. Ensure all your ingredients are ready to streamline the cooking process.

Step 2: Sauté Vegetables
Set your Instant Pot to the sauté function and add a splash of olive oil. Once heated, toss in your chopped zucchini and bell peppers, sautéing for about 5 minutes or until the vegetables soften and become slightly translucent. This step enriches the flavor base of your Easy Vegetarian Low-Carb Casserole, making it more delicious.

Step 3: Mix Base
After the veggies are tender, stir in the cream cheese, allowing it to melt and blend seamlessly into the mixture. This should take about 2-3 minutes. Once well combined, add the cauliflower rice and spinach to the pot, stirring thoroughly to coat everything in the creamy goodness. The filling will start to take shape, inviting and vibrant!

Step 4: Add Cheese and Seasoning
Sprinkle in the shredded cheddar cheese along with the Italian seasoning, stirring until everything is uniformly distributed. The cheese will start melting from the residual heat, adding a rich flavor profile to your casserole. Make sure there are no clumps, and everything is well mixed, which will ensure even cooking next.

Step 5: Pressure Cook
Seal the Instant Pot lid and set it to cook on high pressure for 10 minutes. As the cooking progresses, you might hear the sound of steam, which is perfectly normal. Once the time is complete, allow the pressure to release naturally for 5 minutes before carefully switching the valve to release any remaining steam. Your Easy Vegetarian Low-Carb Casserole is almost ready!

Step 6: Serve
Open the Instant Pot and fluff the casserole gently with a fork to mix the textures. For an extra touch of flavor, consider garnishing with additional cheddar cheese or fresh herbs like basil. Serve warm and watch as your family digs into this comforting dish, complete with all its rich flavors and vibrant colors!

Storage Tips for Easy Vegetarian Low-Carb Casserole

Fridge: Store any leftovers in an airtight container in the fridge for up to 4 days to maintain freshness and flavor.

Freezer: You can freeze the casserole for up to 3 months. Ensure it’s cooled completely before transferring it to an airtight freezer-safe container.

Reheating: For best results, reheat individual portions in the oven at 350°F until warm, or use the microwave for a quicker option, adding a splash of vegetable broth to keep it moist.

Marsala Sauce Storage: If you’ve made the savory Marsala sauce alongside your casserole, store it separately in the fridge for up to a week or freeze for up to 3 months in a sealed container.

Make Ahead Options

This Easy Vegetarian Low-Carb Casserole is perfect for meal prep! You can prepare all the ingredients up to 24 hours in advance. Simply chop the zucchini, bell peppers, and spinach, then store them in an airtight container in the refrigerator to maintain freshness. If using fresh cauliflower, ricing it ahead of time and refrigerating is also a great option. When you’re ready to enjoy your casserole, just sauté the prepped veggies in the Instant Pot, mix in the cream cheese, cauliflower rice, and seasoning, then pressure cook as directed. This prep method saves you valuable time on busy weeknights while ensuring a delicious and satisfying meal awaits the moment you come home!
