A hearty, cozy vegan grits casserole with sautéed mushrooms that taste like sausage! It's a perfect breakfast or brunch casserole for a weekend morning.

This sausage-y cheesy vegan grits caserole is perfect for treating your friends and family to a comfort food brunch. It's easy to make, and there's only one pot to clean after you clean your plate!
One thing you should know about this recipe: it is NOT health food. It's greasy, a little bit salty, and I wouldn't have it any other way. Cheese grits are supposed to be decadent!
To minimize the number of pans you'll need for this recipe, you make the sausage mushrooms in your 3.5 quart Dutch oven (or a similar-sized pot that can go from stovetop to oven), then reuse the same pot to cook the grits.
Rinse the pan between uses, but don't worry about totally cleaning it out. A little bit of the sausage seasoning in the grits won't hurt anything.
Ingredients and substitutions
- olive oil - To sauté.
- button mushrooms - This is going to be your "sausage."
- smoked paprika - Gives the mushrooms a smoky, umami flavor.
- garlic powder - Makes things delicious!
- fennel seeds - This really brings the sausage flavor.
- quick grits - You want the kind that cook in five minutes. You can use regular grits and just follow the directions for four servings, but I don't recommend using instant grits.
- baby spinach - Or other quick wilting greens.
- vegan cheese shreds - These go into the grits AND on top! Use your favorite: mozzarella, cheddar, pepper jack, etc!
How to make vegan grits casserole
Preheat the oven to 350° F, then make the sausage mushrooms.
Heat a Dutch oven to medium-high heat. Add the mushrooms, salt, and all of the spices and cook, stirring, for about seven to nine minutes, until the mushrooms soften and begin to brown. Transfer to a small bowl and set aside.
Rinse out the pan and return it to the stove. You don't have to scrub it, just give it a good rinse.
Now, make the vegan cheese grits.
Add the water to the same pot you used for the mushrooms, and bring it to a boil. Add the grits, and cook on medium-low, covered and stirring occasionally, for five to seven minutes, until they thicken.
When the grits are done cooking, turn off the heat and add the vegan butter, spinach, a cup of the vegan cheese shreds, and the cooked mushrooms to the pan. Stir well to melt the butter and cheese and wilt the spinach.
Top with the remaining cheese, and bake the vegan grits casserole for 25 minutes, until the cheese is melted.
Helpful tips
- Rinsing the pan between cooking the mushrooms and the grits just gets rid of any excess seasoning which would give your grits a reddish color.
- Do be sure to stir the grits a few times as they cook, scraping the bottom of the pan when you do. Stirring prevents lumps and scraping keeps the grits from sticking to the bottom as they cook.
Storage directions
Store leftovers either in the pan you cooked in or in an airtight container. They'll keep for three to four days. Reheat in the microwave until warmed through.
Frequently asked questions
Oh my gosh, so many things! I love adding veggies, like spinach or corn. You can add non-dairy cheese. And, of course, you want to use salt and black pepper!
