Before losing 125 pounds, I thought every vegetable should be covered in cheese. I used cheese as a “flavor booster,” thinking it was harmless. Now that I know better, I still like covering some vegetables in “cheese”, but I choose dairy-free cheese.

That’s why I created this Cheesy Low Carb Brussel Sprout Casserole. It’s rich, velvety, loaded with cheesy goodness, and still completely dairy-free thanks to my Cheezy Bliss Sprinkle cheese powder.

It’s the perfect side dish for weeknights or holiday meals, but I’ve eaten it as a main course more than once. No shame.

It’s also one of the easiest low-carb recipes to slide right into your meal plan. With simple ingredients, a dreamy creamy sauce, and a crispy, golden brown top, it’s basically a dairy-free au gratin moment — except without all the carbs or heaviness.

How to Make This Cheesy Brussel Sprouts Recipe

Follow these easy steps for the best results:

Step 1: Prepare the Brussel Sprouts

Trim the bottom, and peel off the outer layer, slice in half, and toss them in olive oil, sea salt, and black pepper. Spread them in a single layer on a safe skillet or baking sheet.

Roast at medium-high heat in a preheated oven (400°F) until the top of the roasted brussel sprouts starts to turn golden brown. This gives you crispy brussels sprouts instead of mushy ones.

Step 2: Make the Dairy-Free Creamy Sauce

In a medium saucepan over medium heat, whisk together the plant milk, vinegar, Dijon mustard, and Cheezy Bliss Sprinkle, cooking until the mixture slightly thickens.

Step 3: Combine

Place the roasted, tender brussel sprouts in a greased casserole dish. Pour the creamy cheese sauce over the top and gently toss until everything is coated.

Step 4: Add the Topping

In a small dish, combine panko bread crumbs and nutritional yeast. Spread over the top of the casserole for a delicious way to add crunch. Spritz the top with olive oil.

Step 5: Bake

Bake until the edges bubble and the top turns perfectly golden brown – usually 12-15 minutes.

Step 6: Serve & Enjoy

Serve this keto brussel sprout casserole warm alongside your favorite low-carb vegetable dishes, this incredible Chicken Seitan, or enjoy it as a delicious main dish.

How to Store

Let cool to room temperature, then store in an airtight container for 3–4 days. Reheat in the oven or air fryer until warmed through.
