This brussels sprout gratin was the ‘main event’ for our Thanksgiving meal this year, and I plan to make it again for regular dinner meal prep! With the flavors of gruyere, and tender but flavorful Brussels sprouts, I honestly think this beats my traditional carb bomb baked mac and cheese. Plus, it reheated beautifully in a 350F oven.
True story: I had to look up whether it was ‘brussels’ or ‘brussel’ – its Brussels with a capital B, so I was wrong all around.
Ingredients:
- 2 cups (1/2 pound) brussels sprouts, sliced
- or purchase shredded if you can find them
- 2 cloves garlic (or 1/2 tsp garlic powder)
- Olive oil
- 2oz (1/2 cup) gruyere, shredded
- 2 tbsp butter
- 1 tbsp flax meal
- 1 tbsp coconut flour
- 1 cup heavy cream (1/2 container)
- 1/2 tsp thyme
Instructions:
Preheat oven to 400°F.
Heat a skillet over medium heat. Cook the garlic and brussels sprouts in olive oil until bright green and wilted.

Meanwhile, in a small saucepan melt butter. Add flax meal and coconut flour and stir until cooked. Add cream and thyme and heat, stirring, until steaming but do not boil. Basically, you’re making a keto roux here.
If you cooked the brussels sprouts in a cast iron skillet you can leave them there. If not, place the brussels sprouts in a baking dish (we doubled the recipe and used a 9×13). Top with half the cheese, then pour over cream sauce, and top with remaining half of cheese.

Bake for 12-15 minutes, until bubbly and browned.

Note for meat eaters: an excellent version of this involves cooking bacon, removing and then cooking the brussels sprouts in the bacon grease. You can add chopped bacon bits in before popping in the oven.
