What are Brussels sprouts

I never fully understood what Brussels sprouts were until I was walking through a farmer’s market in Belgium and came across this huge stalk of cabbage-like balls.

That’s when I realized both how they grew and why they were called Brussels sprouts (Brussels is the capital of Belgium).

I have another recipe on my site for how to cook the full stalk of sprouts, but most of the time, you’ll find the vegetable already removed from the stem and sold individually in the grocery store.

The sprouts are cruciferous vegetables, similar to cabbage and cauliflower. They can taste a little bitter and skunky, if not cooked properly.

But when you season the tiny cabbages and cook them in the Ninja Grill, the outer leaves will crisp up and the centers will almost melt in your mouth, making them both a healthy and delicious side that’s sure to become a family favorite.

Ingredients

  • Brussels Sprouts: The recipe calls for 2 pounds of fresh Brussels sprouts. You can usually find these in the vegetable section of your grocery store.
  • Olive Oil: This will help crisp the the leaves of the sprouts.
  • Balsamic Vinegar: The vinegar will add a nice tartness to your sprouts. You can also use apple cider vinegar or red wine vinegar.
  • Salt and Pepper: You can also use other herbs and seasonings to expand the flavors. Cumin, garlic powder or lemon pepper are nice options.
Substitutions: In place of the olive oil and balsamic vinegar, you can also use bottled vinegar-based salad dressing.

NINJA PRO TIP: To test if the sprouts are done, pierce a fork in the center of the cores or use an instant read thermometer and look for an internal temperature of 185-190F degrees.

How to serve grilled Brussels sprouts

Once the crispy sprouts are cooked through, remove the air crisp basket from the grill and pour them into a serving bowl. Sprinkle with some added salt and pepper to taste.

If you want to add even more flavor, a drizzle of bottled balsamic glaze, maple syrup or a squeeze of lemon juice is a perfect addition. You can also sprinkle on a little parmesan cheese or goat cheese.

Storage

Brussels sprouts are best when they are eaten right away, but you can also save them in an airtight container in the refrigerator for 3-5 days.

Reheat them in the microwave or in a Ninja Grill set to the air crisp function at 375F degrees, until warmed through.

Grilled Brussels sprouts don’t freeze and reheat very well, so only cook as many as you can eat within the week.

Frequently Asked Questions

Why won’t my Brussels sprouts get crispy?

If you cook your sprouts at 400F degrees on the Ninja Grill with it set to air crisp, you shouldn’t have any problems with the leaves getting crispy. The convection in the grill will circulate the hot air. If you cook at a lower setting, they may not crisp up as much.

Do you need to soak Brussels sprouts before cooking?

There is no need to soak them. It’s best to rinse them and remove any extra wrinkly or brown leaves, but otherwise, prep is really simple. Just slice, season and cook.

Can I add bacon to this recipe?

Yes, my friend. You can add bacon to any recipe. It’s the perfect food. If you do want to add bacon, I recommend dicing it and mixing it in with the sprouts after they’ve cooked for about 5 minutes.

Are they called Brussel sprouts or Brussels sprouts?

Technically, they are named after the capital of Belgium, which is Brussels. So the correct term is Brussels sprouts.
