25 Best Vegetarian Casserole Recipes

Few things are easier or tastier than a good casserole. Casseroles make an easy meal prep item to have on hand during those busy weeks and they freeze like a dream! Common vegetarian ingredients like broccoli, mushrooms, kale, macaroni noodles and proteins like cheese and tofu can be easily transformed into hearty and filling weeknight meals. I’ve compiled some of my favorite vegetarian casserole recipes below, many of which are also vegan, dairy-free and easily made gluten-free with a minor substitute. I hope you enjoy this collection of true comfort food!

❓What is a casserole?

A casserole is simply a dish made of a mixture of a variety of ingredients that are combined, then slowly cooked in an oven.

❓Should you freeze a casserole before or after you cook it?

For best results, freeze a casserole prior to baking to maintain the best textures. However, if you’ve already cooked a casserole, you most definitely can freeze it and maintain the leftovers for longer.

❓How do you freeze casseroles?

Line a freezer-safe casserole dish with parchment paper or aluminum foil, assemble your casserole ingredients over the lining, then pop the container into the freezer until set. Remove the container from the freezer then lift the solid casserole and place it into a freezer-safe container with an airtight lid.

❓How do you cook a frozen casserole?

Remove a frozen casserole from the oven and allow to thaw at room temperature for a few hours before cooking according to recipe instructions.
