🥘Keto Brussels Sprouts Gratin Ingredients
These are the ingredients necessary to make Keto Brussels Sprouts Gratin.
- Brussels Sprouts - Choose firm, compact Brussels sprouts with bright green, unblemished leaves. Smaller sprouts tend to be sweeter, while larger ones can be milder in flavor.
- Gruyere Cheese - I prefer Gruyere's more assertive nutty flavor for this recipe but you can use Swiss if you prefer or cannot find Gruyere.
- Keto Breadcrumbs - Please see the notes as to how to make keto breadcrumbs.
A detailed list with measurements and instructions can be found on the printable recipe card at the bottom of the page.
🔪Keto Brussels Sprouts Gratin Instructions
This is a basic breakdown of the steps involved in making Keto Brussels Sprouts Gratin. You will find the full directions in the recipe card at the bottom of the post.
Butter a cast iron skillet or a small casserole dish. Add the Brussels sprouts and spray with olive oil and then season with salt and pepper.
Add the thyme, salt, pepper, parmesan cheese, and 1 cup of shredded cheese and stir until the cheese is melted and incorporated into the sauce.
Pour the cheese sauce over the Brussels sprouts.
Top with the remaining shredded cheese and breadcrumbs.
Helpful Hint: 💡: When preparing the keto breadcrumbs, ensure your keto bread is toasted to medium for optimal flavor and texture. It should be dry but not burnt.
Substitutions
- Cheese - If you prefer you can experiment with different cheese varieties to customize the flavor. Try a blend of sharp cheddar and Gruyère for added depth, or use Swiss cheese for a milder taste.
- Vegan - You can substitute coconut milk and plant-based cheeses to make this a vegan-friendly dish.
- Breadcrumbs - You can substitute the keto breadcrumbs with crushed pork rinds if you do not have any keto bread.
📖Variations
- Nutty Twist - Add a delightful nutty flavor by incorporating chopped toasted almonds or hazelnuts into the breadcrumb topping.
- Spicy Kick - For those who enjoy a bit of heat, incorporate crushed red pepper flakes into the garlic-butter sauce or sprinkle them over the gratin before baking.
- Protein Boost - Integrate cooked and crumbled sausage or diced cooked chicken to turn this side dish into a complete, protein-packed meal.
🍽Equipment
This is the equipment you will need to make Keto Brussels Sprouts Gratin.
Storage
Refrigerator: Store any leftover Keto Brussels Sprouts Gratin in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven or microwave until warmed through.
Freezing: While Brussels sprouts can lose some of their texture when frozen, you can freeze the gratin for later consumption. Place individual servings in freezer-safe containers, separating layers with parchment paper. Label with the date and store for up to 2-3 months. To reheat, thaw overnight in the refrigerator and warm in the oven to help retain the texture.
Note: Keep in mind that the cream-based sauce may undergo texture changes upon thawing, so the reheated dish might not be as creamy as the freshly made version.
💭Top tip
For a festive touch, consider adding a sprinkle of fresh thyme leaves as a garnish when serving this Keto Brussels Sprouts Gratin. It not only enhances the visual appeal but also complements the dish's flavors beautifully.
FAQ about Keto Brussels Sprouts Gratin
Absolutely! Prepare the Brussels sprouts and the cream sauce in advance. Assemble the gratin, cover, and refrigerate. Before serving, add the topping and bake for a delicious, stress-free side dish.
You can substitute crushed pork rinds for the keto breadcrumbs. They provide a similar texture while keeping the dish low-carb.
