    Easy Cheesy Brussels Sprouts

    When you’re not in the mood to make something fancy or complicated, these creamy brussel sprouts are the perfect side dish! All you have to do is toss the ingredients in a bowl and then pop them into a cast-iron skillet or baking dish. They’re pretty much effortless and still turn out super creamy, rich, and decadent.

    Magical things will happen during baking. For starters, the garlic will infuse all of its pungent spiciness into the heavy cream. The cheese will melt and caramelize on top. This creates a crispy exterior with a bit of sharpness to it. To balance the creaminess, a bit of Italian seasoning ties everything together with its earthy, herbal notes.

    Baked until bubbly and melty, it’s an amazing side to serve with your favorite mains. It’s also delicious on its own with garlic bread! Ready in less than 30 minutes and made in one-pan, they’ll taste like you spent the entire in the kitchen.

    What You’ll Need

    Brussel sprouts, heavy cream, and cheese. Everything else just adds a ton of flavor so don’t skip it. Exact ingredient amounts are in the recipe card at the bottom of this post.

    • Brussel sprouts
    • Heavy cream – Feel free to use half-and-half, béchamel, or Alfredo sauce. Stay away from milk because it’s too runny and won’t thicken.
    • Garlic – Nothing beats freshly minced garlic. However, you can substitute it for 1/4 tsp of garlic powder for every clove in the recipe.
    • Italian seasoning – Use store-bought or make your own Italian seasoning by mixing 2 tbsp of dried basil, 2 tbsp dried oregano, 3 tsp red pepper flakes, 2 tbsp dried rosemary, and 2 tbsp dried thyme. You can also leave it out completely.
    • Salt and pepper
    • Parmesan cheese – If needed, swap it for Asiago cheese.
    • Mozzarella cheese – Provolone, Muenster, cheddar, Gruyere, and Swiss cheese are good options too. Use a mix of them if you want!

    How to Make Creamy Baked Brussels Sprouts

    There are only 5 easy steps to the perfect, creamy side dish. Here’s everything you need to do:

    • Prepare the skillet. Preheat the oven to 400F. Grease a cast-iron skillet with butter or olive oil. Set it aside. You can also use an oven-friendly small casserole dish.
    • Combine. Toss all the ingredients in a large bowl until well combined. Transfer them to the prepared skillet.

    • Sprinkle cheese. Add extra cheese on top! I love parmesan and mozzarella, but you can use up any leftovers you have in the fridge like shredded cheddar and Muenster.
    • Bake. Pop the skillet into the oven and let the brussel sprouts bake for 25-30 minutes or until bubbly and melty. The brussel sprouts should have browned edges.
    • Serve. Remove the skillet from the oven and let it rest for 5-10 minutes before serving. Enjoy!

    Tips for Success

    Follow these tips to make sure your brussel sprouts are so perfectly cooked everyone asks for seconds:

    • Use other veggies. Asparagus, mushrooms, broccoli, and cauliflower are great substitutes for brussel sprouts. It’s also an easy way to use up leftovers, just don’t mix them because vegetables have different cooking times.
    • Don’t overcook. Leaving them in the oven for longer will soften them too much or burn them. When the sauce is bubbly and the cheese has melted, they’re ready.
    • Watch the salt. Cheese has lots of salt in it, so I recommend waiting for it to melt before you decide to add more salt to the dish.
    • Use a baking dish. If you don’t have a cast-iron skillet, don’t worry. Baking dishes will get the job done too.
    • Make sure they’re similar sizes. When picking your brussel sprouts, make sure they’re more or less the same size. This will ensure even cooking.

    What to Serve With Parmesan Brussels Sprouts

    With loads of melted cheese, the only things that could make these creamy baked brussel sprouts better are some flavor-packed toppings.

    Bits of crunchy bacon, chopped jalapeño, and crispy oven-baked panko can easily add loads of smokiness, crunch, and spiciness.

    Enjoy it with garlic bread and all your favorite mains, like my Baked Honey Mustard Chicken, Juicy Flank Steak, and Red Wine Braised Short Ribs.

    How to Store & Reheat Leftovers

    Once cooled, pop them into an airtight container and refrigerate for up to 3 days.

    To reheat, drizzle a little bit of milk on top and microwave it for 1-3 minutes or until warm. Sprinkling a little bit of cheese on top and placing it under the broiler for up to 1 minute will also create that crispy cheese exterior again.
