Extra toppings for this recipe
Toppings are a great way to really make this dish your own!
If you’re not worried about staying keto, fried onions are a traditional topping that add flavor and crunch. You could also add some low-carb breadcrumbs for an even heartier top layer.
If you want to keep this dish low carb, try experimenting with different flavors of cheese on top. If you ask me, more cheese can ALWAYS make a recipe better! 🙂
There are a few different ways to change up the base of this recipe.
First, while I like to use my vegan mushroom soup, you can easily substitute with any mushroom soup you like. Whether you have your own favorite family recipe for cream of mushroom soup or simply want to make things easy by using a can of mushroom soup, it’s totally up to you!
You can also sneak in extra low-carb vegetables to add even more nutrition and flavor to this recipe. Bell peppers, asparagus, zucchini, cauliflower, and broccoli are all great low carb vegetables to add that will bring a whole different kind of flavor to this bake.
Preparing the recipe in advance
If you’re planning to make this dish for friends and family, you probably don’t want to spend a bunch of time in the kitchen getting it ready.
Great news: you can prepare this casserole up to 24 hours in advance!
Simply follow the steps to make and assemble the casserole, but don’t bake it yet. Instead, cover with a lid or plastic wrap and place in the refrigerator.
Once you’re ready, just take the prepared casserole out of the refrigerator, remove the cover, allow it to sit for about 5 minutes, then bake as usual!
Leftovers can be stored covered in the refrigerator for up to 5 days.
To reheat, I recommend removing a serving from the refrigerator and allowing it to sit at room temperature for about 30 minutes, then placing it back in the oven at 350F until it’s nice and bubbly.
