Whole30 Chicken Broccoli Casserole

While many people seek out Whole30 recipes as part of a January or September Whole30 reset (the months most do the program), I like to remind folks that Whole30 recipes are still delicious every day of the week. They’re just free of gluten, grains, dairy, sugar and legumes. But they’re certainly not lacking in flavor.

In fact, I’d wager to guess most people think this recipe has dairy, because it’s super creamy and cheesy-like. You can thank my Vegan Alfredo Sauce recipe for that (which on it’s own is a reader favorite recipe).

How to Make this Whole30 Casserole Recipe

Make the Vegan Alfredo Sauce

The most important thing in this recipe is remembering to soak your cashews overnight for the sauce. You could also make the entire Vegan Alfredo Sauce recipe the day before and store it in the fridge until you’re ready. Or you could make it same day. It’s entirely up to you.

Make the Shredded Chicken

Cook the chicken on the stovetop, then transfer the chicken breasts to a stand mixer with a paddle attachment. Turn the stand mixer on low for 15 seconds and you have the easiest shredded chicken ever. If you don’t have a stand mixer you could use two forks to shred. But if you do have a stand mixer, this is one of my favorite kitchen hacks.

Sauté the Vegetables

Quickly sauté the mushrooms and diced onion, then add the broccoli and sauté a few minutes longer until it’s crisp tender. Super easy.

Assemble the Casserole

Once all of the individual pieces are done, it’s simply a matter of assembly. Add the shredded chicken to the bottom of a casserole dish, then layer on the broccoli and mushrooms. Pour on the Vegan Alfredo Sauce (that’s thinned with a cup of chicken broth) and bake the casserole for 20-25 minutes in a 400F oven.

When the casserole comes out of the oven it’s bubbly, tender, creamy, savory and so delicious you’ll definitely go back for seconds. Enjoy!
