How To Make A Brussels Sprout Casserole
Let’s get to this keto brussels sprouts casserole! Will you believe me when I tell you that it takes just 10 minutes to prep?! It’s true!
Here’s how to make brussels sprout casserole with bacon:
- Roast brussels sprouts. Toss the brussels sprouts with olive oil, season with salt and pepper and roast until edges are brown and crispy.
TIP: Be sure the sprouts are spread out in a single layer on the pan, otherwise they won’t brown well.
- Make cheese sauce base. Melt butter, then mix in almond milk and heavy cream. Heat until hot. Stir in shredded cheddar cheese, until melted.
TIP: It will be somewhat runny, which is okay. It will absorb into the sprouts and thicken more as it bakes and then cools a bit before eating.
- Assemble the low carb brussels sprouts casserole. Transfer the brussels sprouts to a stoneware dish. Pour cheese sauce over brussels sprouts and top with more cheese, and of course, bacon!
TIP: You can make bacon in the oven and chop or crumble it, or use store bought bacon bits if you want to save time. Either way, just make sure the bacon is cooked.
- Bake. Since everything is already cooked, this is just long enough to heat and melt the cheese.

Preheat the oven to 400 degrees F (204 degrees C). Line two 9x13 in (23x33 cm) pans with foil, parchment paper, or silicone mats.
Toss the brussels sprouts with olive oil. Season with half of the sea salt and black pepper. Arrange on the pans in a single layer. Roast side-by-side for 35-45 minutes, rotating halfway through, until edges are browned and crispy.
- Meanwhile, melt the butter in a bowl in the microwave or in a saucepan on the stove. Add the almond milk and heavy cream. Heat again until hot.
- Stir in one cup (2/3 of the recipe) of the shredded cheddar cheese, until melted. Season with the remaining sea salt and black pepper.
When the brussels sprouts are finished roasting, transfer them into a smaller 8x11 in (20x28 cm) or 9x9 in (23x23 cm) pan (line it unless it's ceramic or stoneware). Pour the sauce over the brussels sprouts. Sprinkle bacon bits and the remaining shredded cheese on top.
Bake for 10-15 minutes, until bubbly.
