Brussels Sprouts Gratin

by Organo Republic 21 Feb 2022

Today we’re starting with a delicious Brussels sprouts gratin. This dish is bursting with fall flavors and is pure comfort food. It tastes amazing when served with a glass of Amity Pinot Noir. The combination of tender Brussels sprouts, earthy mushrooms, crispy bacon, and a rich creamy sauce topped with a crunchy cheesy walnut mixture makes this gratin a standout dish for any occasion.

Ingredients

Topping

  • 4 slices thick-cut bacon, finely chopped
  • 1 medium-sized onion, diced
  • ½ cup walnuts
  • ½ cup parsley, finely chopped
  • ½ cup shredded extra-sharp cheddar cheese

Brussels Sprouts

  • Salt (for the cooking water)
  • 1 pound Brussels sprouts, sliced in half
  • 2 tablespoons unsalted butter
  • 12 ounces mushrooms (any variety or mix works well – portobello, button, porcini, chanterelle), roughly chopped
  • Hefty pinch of freshly ground black pepper
  • 2 cloves garlic, minced
  • ¼ teaspoon freshly ground nutmeg
  • 2 tablespoons all-purpose flour
  • 1 cup chicken broth
  • 1 cup heavy cream

Directions

Preheat the Oven

  1. Set the Temperature:
    Preheat your oven to 475°F (245°C).

Prepare the Topping

  1. Cook the Bacon:
    In a large cast iron skillet, cook the chopped bacon over medium heat until it’s cooked through and lightly crisp. The bacon will cook a little more in the oven, so it doesn’t need to be extra crispy at this stage.
  2. Drain the Bacon:
    Use a slotted spoon to remove the bacon from the pan and place it on a paper towel-lined plate to drain.
  3. Sauté the Onion:
    In the same skillet, add the diced onion to the bacon drippings (you should have about 1 tablespoon of drippings; if there's more, pour out the excess and save it for future use). Cook the onion until soft and tender, about 8 minutes. Remove the onion from the pan and place it in a bowl.
  4. Toast the Walnuts:
    Add the walnuts to the skillet and cook, shaking the pan often, until the walnuts are lightly golden, about 5 minutes. Transfer the walnuts to the bowl with the onion, then add the cooked bacon.
  5. Combine Topping Ingredients:
    Add the chopped parsley and shredded cheddar cheese to the bowl and toss the mixture. Set the topping aside.

Blanch the Brussels Sprouts

  1. Boil the Water:
    Bring a large pot of salted water to a boil. Add the halved Brussels sprouts and blanch them for 5 minutes. This will help to soften the sprouts and reduce some of their bitterness.
  2. Cool the Sprouts:
    Drain the Brussels sprouts in a colander and immediately plunge them into a large bowl of ice water to stop cooking. Drain the sprouts again and set them aside.

Cook the Mushrooms

  1. Heat the Skillet:
    Wipe out the cast iron skillet you used earlier as you’ll be using it again.
  2. Sauté the Mushrooms:
    Melt the butter in the skillet over medium-high heat. Add the chopped mushrooms along with a hefty pinch of salt and pepper. Cook, stirring occasionally, until the mushrooms release their liquid, about 4 to 5 minutes.
  3. Add Garlic and Nutmeg:
    Add the minced garlic and ground nutmeg to the skillet and cook for another 1 to 2 minutes until fragrant.

Make the Cream Sauce

  1. Cook the Flour:
    Sprinkle the flour over the mushroom mixture and stir to combine. Cook the flour for 1 minute to remove the raw taste.
  2. Add the Broth:
    Add the chicken broth and bring the mixture to a simmer. Cook for about 1 minute, allowing the broth to slightly reduce.
  3. Add the Cream:
    Lower the heat to medium-low and pour in the heavy cream. Continue cooking, stirring occasionally, until the sauce thickens, approximately 6 to 8 minutes.

Assemble the Gratin

  1. Mix with Brussels Sprouts:
    Remove the skillet from the heat and gently stir in the blanched Brussels sprouts until they are evenly coated with the creamy mushroom sauce.
  2. Add the Topping:
    Evenly sprinkle the bacon, onion, walnut, and cheese topping over the Brussels sprouts.

Bake the Gratin

  1. Bake:
    Place the skillet in the preheated oven and bake the gratin until it is bubbly and the topping is golden brown, about 15 minutes.

Serve

  1. Cool and Serve:
    Once baked, remove the gratin from the oven and allow it to cool slightly before serving. The dish pairs beautifully with a glass of Pinot Noir, making it a perfect cozy meal for fall.

Additional Tips

  • Make Ahead: The Brussels sprouts and mushroom mixture can be prepared in advance and stored in the refrigerator. Assemble the gratin just before baking.
  • Variation: For an added twist, you can sprinkle some grated Parmesan or Gruyère cheese on top before baking for an extra cheesy crust.
  • Serving Suggestions: This gratin can be served as a side dish with roasted meats or as a main course alongside a fresh green salad.

This Brussels Sprouts Gratin is a rich, flavorful dish that captures the essence of comfort food while showcasing the earthy, nutty flavors of fall ingredients. Enjoy it warm with loved ones for a memorable dining experience.
