Easy Brussels Sprouts Casserole Recipe

This Brussels sprouts casserole is one of those dishes that has a way of winning over even the most ardent Brussels sprout skeptics. It’s creamy, savory, and just a little bit cheesy, with a hint of smoky beef bacon that really makes the vegetables sing. I love making this for weeknight dinners when I want something comforting but also packed with good-for-you greens, or for potlucks because it always disappears fast. The key is balancing the slight bitterness of the sprouts with richness and savory notes.

Ingredients:

• 4 slices beef bacon, cooked and crumbled (or 4 tablespoons of Real Beef Bacon Bits)
• 2 tbsp butter
• 2 shallots, minced
• 2 garlic cloves, minced
• 2 lb Brussels sprouts, cleaned and halved
• ¼ tsp cayenne pepper
• ½ tsp mustard powder
• Salt and freshly ground pepper to taste
• 1 cup heavy cream
• ½ cup sharp white cheddar, shredded
• ½ cup shredded Gruyere, shredded

Cooking Instructions:

1. Prep the Sprouts and Aromatics: Start by getting your Brussels sprouts ready. You want to trim off the tough end of each sprout and then cut them in half lengthwise. If you have any really large ones, you can quarter them so they cook more evenly with the smaller ones. For the aromatics, mince your shallots and garlic. Mincing finely helps them release their flavor into the butter without becoming bitter or burning easily. Have your beef bacon cooked and crumbled or your beef bacon bits measured out. This dish benefits from that salty, smoky crunch.
2. Sauté the Aromatics and Sprouts: In a large oven-safe skillet or a Dutch oven over medium heat, melt the 2 tablespoons of butter. Once the butter is melted and slightly foamy, add the minced shallots. Cook them, stirring occasionally, until they become softened and translucent, which usually takes about 3-4 minutes. You don’t want them to brown too much at this stage. Then, add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic, as burnt garlic can taste bitter. Now, add the halved Brussels sprouts to the skillet. Season them generously with salt and freshly ground black pepper, the ¼ teaspoon of cayenne pepper, and the ½ teaspoon of mustard powder. Stir everything together to coat the sprouts evenly with the butter, shallots, garlic, and seasonings. Cook for about 5-7 minutes, stirring frequently, until the sprouts start to soften slightly and get a little color on their cut sides. This step helps to mellow out the raw flavor of the sprouts and build a good flavor base.
3. Add the Cream and Cheese: Once the Brussels sprouts have had a chance to soften and get a little color, pour in the 1 cup of heavy cream. Stir it into the skillet, scraping up any bits that might have stuck to the bottom. Bring the mixture to a gentle simmer. Let it simmer for about 5 minutes, allowing the cream to thicken slightly and the sprouts to continue cooking. The sprouts should be tender-crisp at this point. Now, stir in half of the shredded sharp white cheddar and half of the shredded Gruyere cheese. Stir until the cheese is melted and the sauce is smooth and creamy. You’ll notice the sauce starting to coat the sprouts beautifully. Taste and adjust the salt and pepper if needed. Remember that the beef bacon you add later will also contribute saltiness, so don’t oversalt at this stage.
4. Top and Bake: Preheat your oven to 375°F (190°C). Sprinkle the remaining sharp white cheddar and Gruyere cheese evenly over the top of the Brussels sprouts mixture. Then, scatter the crumbled beef bacon (or beef bacon bits) over the cheese. The beef bacon adds a wonderful salty, smoky crunch that complements the creamy sprouts and melted cheese perfectly. Place the oven-safe skillet or Dutch oven into the preheated oven. Bake for 15-20 minutes, or until the cheese on top is melted, bubbly, and has started to turn a lovely golden brown. The edges of the casserole should be bubbling gently, indicating it’s heated through and the flavors have melded. Keep an eye on it to prevent the cheese from burning. If the top is browning too quickly, you can loosely tent it with foil.
5. Rest and Serve: Once the casserole is out of the oven, let it rest for about 5-10 minutes before serving. This brief resting period allows the sauce to set up a bit, making it easier to serve and preventing it from being too runny. This casserole is fantastic served as a side dish with roasted chicken, steak, or beef. It’s also hearty enough to be a vegetarian main course if you omit the beef bacon and perhaps add some toasted nuts for crunch. The flavors deepen as it sits, so leftovers are also delicious, though the texture of the sprouts might soften a bit more. You can reheat leftovers gently on the stovetop or in the oven.

Conclusion:

This Easy Brussels Sprouts Casserole Recipe proves that Brussels sprouts can be incredibly delicious and comforting. The creamy sauce, savory beef bacon, and melted cheese coat the tender sprouts perfectly, creating a side dish that’s satisfying enough to be a main course. It’s a fantastic way to get more vegetables onto your plate, especially for picky eaters. Serve it alongside roasted chicken, grilled steak, or beef chops for a complete meal. For a vegetarian option, simply omit the beef bacon and perhaps add some sautéed mushrooms for extra umami. You could also experiment with different cheeses, like adding a bit of smoked gouda for an extra smoky flavor. Don’t be afraid to adjust the seasonings to your liking – a pinch more cayenne or a bit more mustard powder can change the profile slightly. I really encourage you to give this Brussels sprouts casserole a try; it’s a recipe that’s sure to become a regular in your cooking rotation.

Frequently Asked Questions:

Can I make this casserole ahead of time?

Yes, you can assemble the casserole up to a day in advance. Cover it tightly and store it in the refrigerator. You may need to add a few extra minutes to the baking time if it’s cold from the fridge. It’s best to add the beef bacon topping just before baking to keep it nice and crispy.

What can I substitute for beef bacon?

Regular beef beef bacon works perfectly fine. If you prefer not to use beef bacon, you can substitute it with beef pancetta or even some crispy fried onions for a similar crunchy, savory element.

How do I store leftovers?

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the oven or microwave until warmed through.
