Step‑by‑Step Instructions for Easy Low-Carb Vegetarian Casserole
Step 1: Prep Vegetables
Start by preheating your oven to 350°F (175°C). While it warms up, wash and chop your assorted vegetables, like bell peppers, zucchini, and spinach, into bite-sized pieces. The colorful medley will not only provide great flavor but also a delightful presentation. Set the chopped veggies aside in a large mixing bowl for the next step.
Step 2: Mix Ingredients
In the bowl with your prepared vegetables, add the cream of mushroom soup, half of the shredded cheese, and a sprinkle of Italian seasoning, salt, and pepper. Use a spatula to mix everything thoroughly, ensuring all the vegetables are coated in the creamy goodness. This step infuses your Easy Low-Carb Vegetarian Casserole with flavor and moisture for the perfect texture.
Step 3: Assemble Casserole
Grease a 9×13-inch baking dish with cooking spray or olive oil to prevent sticking. Carefully transfer the mixed vegetable filling into the dish, spreading it evenly to create a uniform layer. This ensures that every bite of your casserole is packed with deliciousness. Give it a bit of a shake to settle the mixture nicely.
Step 4: Top Layer
Sprinkle the remaining shredded cheese generously over the vegetable mixture. This will create a beautiful golden crust as it bakes, adding both flavor and visual appeal to your casserole. Make sure to cover the whole surface, as the melted cheese will bind the dish together.
Step 5: Bake
Place your assembled Easy Low-Carb Vegetarian Casserole in the preheated oven and bake for 25-30 minutes. Keep an eye out for a bubbly surface and a golden-brown top, which indicate that it’s ready. Alternatively, if using an Instant Pot, set it to high pressure for 10 minutes, followed by a natural release for tender results.
Step 6: Serve
Once baked, remove the casserole from the oven and allow it to cool slightly for about 5-10 minutes. This cooling period helps the layers set, making it easier to cut the casserole into squares. Serve warm and enjoy the comforting flavors this delicious dish has to offer.
How to Store and Freeze Vegetarian Casserole
Fridge: Store leftovers in an airtight container and refrigerate for up to 4 days, ensuring freshness and flavor retention.
Freezer: For longer storage, wrap the casserole tightly in plastic wrap and then foil, freezing for up to 3 months.
Reheating: To reheat, thaw in the fridge overnight, then bake at 350°F for 20-25 minutes until warmed through and bubbly. The Easy Low-Carb Vegetarian Casserole stays delicious and comforting even after freezing!
Portioning: Consider portioning the casserole before freezing, so you can easily grab individual servings for quick meals any time!

Easy Low-Carb Vegetarian Casserole Recipe FAQs
How do I select the right ripeness for the vegetables?
Absolutely! When choosing vegetables, look for those that are firm and vibrant in color. Bell peppers should be shiny with an even skin, zucchinis should be medium-sized and not too soft, and spinach should look fresh with no browning. When in doubt, seasonal vegetables often taste best!
How should I store the leftovers?
For optimal freshness, store any leftovers in an airtight container in the refrigerator for up to 4 days. This will help maintain the creamy texture and flavors, and when you’re ready to enjoy some more, simply reheat until hot.
Can I freeze the Easy Low-Carb Vegetarian Casserole?
Absolutely! To freeze, allow the casserole to cool completely, then wrap it tightly in plastic wrap followed by aluminum foil. This helps prevent freezer burn. It can last up to 3 months in the freezer. When you’re ready to reheat, thaw it in the fridge overnight and then pop it in the oven at 350°F for about 20-25 minutes until it’s warmed through and bubbly.
What if my casserole turns out too watery?
Very much! If you find your casserole is watery, it may be due to overcrowded vegetables or using high-water content ones. To remedy this, ensure you chop your veggies into similar sizes and avoid using too many soft vegetables. If necessary, after baking, let it sit for a few minutes which can help absorb excess moisture.
Is this recipe suitable for people with nut allergies?
Yes, definitely! The Easy Low-Carb Vegetarian Casserole can be made nut-free by simply omitting any optional nuts or seeds, like walnuts or sunflower seeds. Rest assured, it’ll still be bursting with flavor and deliciously satisfying without them!
Can I use different types of cheese or make it dairy-free?
Very much! You can definitely experiment with different types of cheese to enhance the flavor. For a dairy-free option, I recommend using nutritional yeast or a nut-based cheese, which preserves the dish’s creaminess while keeping it plant-based and delicious.
