Ingredient Notes and Substitutions:

  • Brussels Sprouts: Use small to medium Brussels sprouts.
  • Scallions: You could also use a shallot or two.
  • Dry White Wine: When using wine in cooking, you always want to use a wine you enjoy drinking. Anything with an off-taste can ruin your entire dish. Besides adding flavor, the tartaric acid in wine will help the cheese melt smoothly when you add it. That acid helps break down the cheese proteins for a smoother melt. NON-ALCOHOLIC SUBSTITUTE: Add a teaspoon of white wine vinegar to 1/3 cup chicken or vegetable broth. White wine vinegar has none to only a trace of alcohol.
  • White Cheddar Cheese: I tested this recipe twice–once with a sharp white Cheddar and a second with a mild white Cheddar. We liked the sharp white cheddar version better, but I would avoid an “extra sharp” cheddar because it doesn’t work well with Brussels sprouts.
  • Almonds: Use sliced or slivered almonds. The almonds add a nice crunchy element.
  • Wild Rice Blend: I used Rice Select Royal Blend (affiliate link), available on Amazon and at most grocery stores. Follow the package directions, but be careful not to overcook the rice. Also, the directions say the yield will be 2 1/2 cups, but you will only get 2 cups of cooked rice from their measurements, which is fine for this recipe. (As I mentioned above, I tested the recipe twice.)

Step-by-Step Instructions:

  • Gather and prep all the ingredients.
  • Cook and cool the rice.
  • Preheat the oven to 375 degrees if baking right away. Prepare a baking dish.
  • Prepare an ice bath. Bring a pot of salted water to a boil and drop the Brussels sprouts into the boiling water. Cook briefly, 30-45 seconds, or until they turn bright green. Scoop them out and drop them into the ice bath. Let cool, then drain and pat dry. Discard the cooking water.

  • Heat the butter in the saucepan and add the scallion. Cook until it softens, 2-3 minutes, then add the garlic and cook briefly.

  • Add the flour and cook for 1 minute, then add the white wine. Cook for 1 more minute.

  • Slowly add the half-and-half and bring up to a simmer. Cook for 1 to 2 minutes or until thickened and smooth. (The sauce will not be terribly thick because the cheese will thicken it more.)
  • Stir the rice and Brussels sprouts into the cheese sauce, then pour into the prepared baking dish. Top with the sliced or slivered almonds.
  • MAKE AHEAD:  This Brussels Sprouts Casserole recipe can be prepared to this point 1 to 2 days ahead.  Cool, cover, and refrigerate.  (Be sure the rice is not overcooked, as it will absorb some of the cheese sauce and soften up some more.)  Let stand at room temperature while the oven preheats.  You may need to add baking time if the casserole is cold.

  • Garnish with thyme sprigs or chopped parsley if desired.

Chef Tips and Tricks:

  • When prepping Brussels sprouts, I always wear a disposable glove on my right hand because I tend to nick my thumb, and it gets tender.  (I’m right-handed.) You could also wear a fingertip cot or wrap your thumb in a bandage while trimming and quartering the sprouts if that happens to you, too.
  • To cool the rice quickly, place a sheet pan in the freezer while the rice is cooking. When the rice is done, take the sheet pan out of the freezer and spread the rice over the chilled sheet pan. I also use this method when cooking risotto for personal chef clients to cool it quickly.

Frequently Asked Questions:

How far ahead can I make Brussels Sprouts Casserole?

You can blanch the Brussels sprouts and cook the rice up to 2 days ahead. Cool and refrigerate (the sprouts and rice can be combined). You can also fully assemble the casserole and refrigerate it up to 2 days ahead. Be sure not to overcook the rice because it will absorb some of the cheese sauce as it sits and softens up more.

Can I use other types of rice?

Yes, you can use white, brown or all wild rice.

What other types of cheese can I use?

Rather than white cheddar cheese, you can use Gruyere, Swiss or Monterey Jack.

Can I freeze this Brussels Sprouts Casserole?

For the best result, freeze before baking for 1 to 2 months.  Thaw in the refrigerator.  Bake until heated through and bubbling.  This casserole can also be frozen after baking, but the Brussels sprouts will be very soft.  Thaw in the refrigerator and heat through in a 350-degree oven.

Ingredients
  

  • Cooking spray - for baking dish
  • Salt
  • 1 pound trimmed Brussels sprouts - small to medium size, quartered (4-5 cups after quartering)
  • 3 tablespoons butter - preferably unsalted
  • 1 bunch scallions - white and light green part only, coarsely chopped
  • 2 cloves garlic - minced
  • 1 tablespoon all-purpose flour

Instructions
 

  • Preheat oven to 375 degrees. Spray a large oval gratin dish (1 3/4 to 2-quart) with cooking spray. Set aside.
  • Prepare an ice bath. Bring a saucepan of generously salted water (with approximately 1 tablespoon salt) to a boil. Add the Brussels sprouts and cook for 20-30 seconds or so or until they turn bright green. Scoop them out and drop them into the prepared ice bath to cool. Drain and pat dry.
  • Discard the cooking water, rinse and return the saucepan to the stove.

  • Add the wine and cook for 1 minute.
  • Gradually add the half-and-half and continue whisking until smooth. Bring to a boil. Reduce heat to low and cook 1-2 minutes or until thickened and smooth.
  • Remove from the heat. Add 2 cups of the cheese in increments, whisking as you add the cheese until it's smooth and blended in. Add salt and black pepper to taste.
  • Stir in the rice and Brussels sprouts. Transfer to the prepared baking dish. Top with the remaining 1/4 cup cheese. Sprinkle with the almonds.
  • Bake uncovered for 25-30 minutes or until hot, bubbling and heated through. Serve immediately.

    1. Hi, Luciana, Thanks so much for your question. You could use a plant-based non-dairy coffee creamer that has a neutral flavor. I’d avoid coconut–something more like almond or oat milk. Thanks again and hope you enjoy!
