Step‑by‑Step Instructions for Creamy Mustard Brussels Sprouts Gratin with Smoky Bacon

Step 1: Blanch the Brussels Sprouts
Begin by bringing a large pot of water to a rolling boil and add a pinch of salt. Carefully drop in the halved Brussels sprouts and blanch for 3-4 minutes until they are just tender but not overcooked. Drain the sprouts in a colander, giving them a gentle shake to remove excess water, and set aside to cool slightly.

Step 2: Cook the Bacon
In a large skillet over medium heat, add the diced bacon. Sauté for about 5-7 minutes, or until the bacon is crispy and has released its flavorful fat. Using a slotted spoon, remove the bacon and drain on paper towels, leaving about 1 tablespoon of bacon grease in the skillet for the next step—this will add depth to your creamy mustard Brussels sprouts gratin.

Step 3: Sauté the Onion and Garlic
In the same skillet with the reserved bacon grease, melt 2 tablespoons of butter over medium heat. Add the chopped onion and sauté for 5-7 minutes until they become soft and translucent. Stir in the minced garlic and cook for an additional minute, allowing its aromatic flavors to infuse the oil and onion mixture, setting the base for your creamy sauce.

Step 4: Make the Sauce
Sprinkle in 2 tablespoons of flour to the skillet with the onion and garlic, stirring constantly for about 2 minutes until the flour is lightly browned. Gradually whisk in 2 cups of milk, ensuring a smooth mixture forms. Continue to cook on medium heat, stirring frequently, until the sauce thickens and coats the back of a spoon, which should take about 5 minutes.

Step 5: Season the Sauce
Once thickened, remove the skillet from heat and stir in a pinch of nutmeg, 2 tablespoons of grainy mustard, and season generously with salt and pepper. Mix in half of the grated Parmigiano Reggiano cheese until melted and well combined, creating a rich, creamy sauce for the Brussels sprouts with smoked bacon.

Step 6: Combine and Transfer
Carefully fold the blanched Brussels sprouts and crispy bacon pieces into the creamy mustard sauce, ensuring every sprout is well coated. Once combined, pour the mixture into a buttered baking dish, spreading it evenly to create a delightful base for the cheesy topping.

Step 7: Prepare the Topping
In a small bowl, combine the remaining grated cheese with 1 cup of panko bread crumbs and a pinch of salt. Toss until the crumbs are well-coated in cheese, then sprinkle this mixture evenly over the Brussels sprouts and sauce in the baking dish, adding a crunchy texture that will contrast beautifully with the creamy base.

Step 8: Bake the Gratin
Preheat your oven to 350°F (180°C). Once ready, place the baking dish in the oven and bake for 15-20 minutes, or until the gratin is bubbling and the top is golden brown and crispy. Keep an eye on it to prevent burning and ensure you achieve that delicious, inviting golden crust typical of a savory Brussels sprouts with smoked bacon dish.

Make Ahead Options

These Creamy Mustard Brussels Sprouts Gratin with Smoky Bacon are perfect for busy home cooks looking to save time during the hectic holiday season! You can prepare the dish by blanching the Brussels sprouts and making the creamy mustard sauce up to 24 hours in advance. Simply refrigerate the sprouts and sauce separately to maintain their quality. When you’re ready to serve, combine them with the crispy bacon and pour the mixture into a baking dish. Top with the panko cheese crust, then bake in a preheated oven at 350°F (180°C) for 15-20 minutes until bubbly and golden brown. This way, you can enjoy a delicious, stress-free meal with minimal effort!

Expert Tips for Brussels Sprouts with Smoked Bacon

Proper Blanching: Ensure Brussels sprouts are blanched just until tender to maintain their vibrant color and flavor. Overcooking can lead to mushy sprouts.
Bacon Choice: For a deeper flavor, use thick-cut bacon that crisps up nicely. Turkey bacon can be a lighter alternative but may not add the same smoky richness.
Creamy Sauce: Whisk the milk gradually into the flour mixture; this helps prevent lumps and creates a smoother sauce. Don’t rush this step for the best creamy texture.
Customize Mustard: Adjust the amount of grainy mustard according to your taste. More mustard delivers robust flavor, while less keeps it milder—find your perfect balance!
Let It Rest: Allow the gratin to cool for a few minutes before serving. This resting period helps set the sauce, making for cleaner slices and an even better presentation.
Storage Tips: If you have leftovers, store the gratin in an airtight container for up to 3 days. For a quick reheat, place it in an oven until warmed through, maintaining its golden crust.

Brussels Sprouts with Smoked Bacon Recipe FAQs

How do I select the best Brussels sprouts?
Absolutely! When picking Brussels sprouts, look for firm, compact sprouts with a vibrant green color. Avoid those with yellowing leaves or dark spots, as these are signs of aging. I recommend choosing smaller sprouts—they tend to be sweeter and more tender!

How should I store leftovers of Brussels sprouts with smoked bacon?
For optimal freshness, store your Brussels sprouts gratin in an airtight container in the refrigerator for up to 3 days. This preserves the creamy texture. When reheating, pop it in the oven to maintain that delightful crunch of the panko topping rather than microwaving it, which can make it soggy.

Can I freeze the Brussels sprouts gratin?
Yes, you can freeze this dish! Cover it tightly with plastic wrap and aluminum foil, and it can be stored in the freezer for up to 2 months. When you’re ready to enjoy it, thaw it in the fridge overnight before reheating to maintain its texture.

What can I do if my sauce is too thick?
If your sauce turns out too thick, don’t worry! Simply whisk in a little extra milk, or even some vegetable broth, over low heat until you reach your desired consistency. This will not only loosen the sauce but also keep it creamy and flavorful.

Are there any dietary considerations for this recipe?
Very! If you’re catering to dietary restrictions, you can easily swap out ingredients. For instance, use turkey bacon or omit it for a vegetarian option, olive oil instead of butter for a dairy-free version, and gluten-free flour if needed. Make sure to check for any allergies, especially with the cheese, which can be replaced with a non-dairy alternative.

Can I make this recipe ahead of time?
Indeed! You can prep the Brussels sprouts gratin a day in advance. Assemble everything in the baking dish, cover it, and refrigerate. Just pop it in the oven before serving for a warm, comforting addition to your table without the last-minute fuss!
