How to Make the Keto Vegetarian Creamy Brussels Sprouts Bake (Step by Step)

Fair warning: this recipe is dangerously easy. Once you realize how little effort it takes, you'll be making it every week.

Step 1: Prep Your Sprouts

Preheat your oven to 400°F (200°C). Trim the ends off your Brussels sprouts and slice them in half lengthwise. Pat them dry — this is the step most people skip, and it makes a real difference for browning.

Step 2: Build the Cream Sauce

In an oven-safe skillet or saucepan over medium heat, melt your butter. Add the minced garlic and cook for about 60 seconds until fragrant (don't let it burn — we've all been there). Pour in the heavy cream and add the cream cheese in small chunks. Stir until smooth and slightly thickened, about 3–4 minutes. Season with salt, pepper, and thyme.

Step 3: Combine and Top

Add the Brussels sprouts to the sauce and toss to coat. If you're using a skillet, you can go straight to the oven. If not, transfer everything to a greased 9×13 baking dish. Scatter the Gruyère and Parmesan over the top.

Step 4: Bake Until Golden

Bake uncovered for 25–30 minutes, until the top is bubbly and golden and the sprouts are fork-tender. For extra browning, pop it under the broiler for the last 2–3 minutes. Trust me on this one — that golden cheese crust is everything.

Tips, Swaps & Variations

You've got this — and you've also got options.

• Dairy-free? Swap heavy cream for full-fat coconut cream and use a vegan cream cheese. The flavor shifts slightly but still works beautifully.
• Add some heat: A pinch of cayenne or extra red pepper flakes takes this from cozy to exciting.
• Make it a full meal: Stir in some halved cherry tomatoes or sautéed mushrooms before baking for more substance.
• Meal prep magic: This bake stores in the fridge for up to 4 days and reheats well at 350°F for 10 minutes.

No judgment here if you eat it cold straight from the fridge. I've done it. It's still great.
