Below is a list of the ingredients you’ll need to gather to make this recipe. Scroll all the way down for the full recipe card with amounts.
- Bacon: The crispy bacon crumbles adds such wonderful flavor.
- Brussels Sprouts: Fresh brussel sprouts are best in my opinion but thawed frozen sprouts can work in a pinch. Remove the outer leaves and trim the stem off and cut the sprouts in half.
- Flour & Milk: Together, they create a thick, creamy sauce that’s irresistible.
- Cheddar Cheese: Sharp cheddar cheese is my favorite to use.
- Seasonings: Onion powder, garlic powder, and pepper add depth and warmth.
- Breadcrumbs & Butter: For a perfect crispy topping. Use regular or seasoned breadcrumbs, crushed butter crackers like Ritz or even corn flakes if you’d like.
1. Swap the sharp cheddar for mozzarella cheese, white cheddar, Swiss cheese, Monterey jack cheese or Colby jack, Gruyere cheese or Pepper Jack cheese. You can also use a blend of a couple of cheeses.
2. Add sautéd mushrooms and onions for extra flavor.
3. Omit the bacon and use olive oil for sautéing.
4. Use gluten-free flour and breadcrumbs.
5. Substitute with dairy-free milk like coconut milk or soy milk and cheese.
6. Add fresh thyme for an aromatic touch
7. Use heavy cream for an even creamier sauce.
8. Add ¼ cup of parmesan cheese to the Panko mixture.
9. For a little heat, add a pinch of red pepper flakes or a dash of hot sauce.
10. Drizzle balsamic glaze over top of the finished casserole if you’d like.
How to Make this Brussels Sprout Casserole
Step 1: Preheat the oven and spray a 9×13 casserole dish with non-stick cooking spray.
Step 2: Cook the bacon in a large skillet until crispy. Then remove the remove the bacon with a slotted spoon and place it on a paper towel lined plate to soak up excess grease. (Pour the bacon grease into a bowl or glass measuring cup to for sautéing).
Step 3: Add a tablespoon or 2 of the bacon grease back to the pan and the add the brussel sprouts and sauté them over medium-high heat for about 7-8 minutes. Then remove them from the pan and place them in a large bowl.
Step 4: Add two more tablespoons of bacon grease and the flour to the pan over medium heat and stir or whisk for a minute to create a roux.
Step 5: Gradually add in the milk, whisking constantly until no lumps are remaining. Remove the pan from the heat and add the shredded cheese and seasonings and stir until smooth. Feel free to double the sauce and cheese if you’d like it extra cheesy.
Step 6: Add the brussel sprouts and bacon back in and stir to coat with the cheese sauce. Season with salt and black pepper if you’d like.
Step 7: Then transfer to the prepared baking dish, sprinkle with breadcrumbs mixture, place in the oven and bake until the cheese is bubbly and topping is golden brown.
- Shredding your own cheese off the block is best for melting and creaminess.
- Make sure the breadcrumbs are evenly coated with the butter for a perfectly crispy topping.
- Whisk continuously while adding milk to avoid lumps in your sauce.
- Use paper towels to drain excess grease from the bacon for a balanced flavor.
- Cook everything in a large oven-safe skillet, large cast iron skillet or dutch oven and just place the whole dish in the oven instead baking it in a casserole dish.
