Ingredients for this keto Brussels sprouts recipe

Basic ingredients for roasted Brussels sprouts

  • 1 pound Brussels sprouts, ends trimmed
  • 1 tablespoon avocado oil
  • 1 tablespoon apple cider vinegar
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • 1 teaspoon sea salt

For the dipping sauce

Dipping sauce made with Greek yogurt and Dijon mustard.
  • ½ cup mayonnaise (or plain Greek yogurt)
  • 1 tablespoon Dijon mustard
  • 1 tablespoon apple cider vinegar
  • 1 tablespoon coconut aminos (or gluten-free tamari)
  • ½ teaspoon sea salt
  • ½ teaspoon of fresh ground black pepper

Ingredient substitutions

  • Avocado oil: Substitute it with olive oil or coconut oil.
  • Apple cider vinegar: You can use white wine vinegar or red wine vinegar instead, as both provide a tangy flavor to the dipping sauce.
  • Garlic powder: You can use fresh garlic for a more pronounced garlic flavor in your dish.
  • Smoked paprika: You can substitute smoked paprika with regular paprika or chili powder, but remember that this will change the dish's flavor profile.
  • Mayonnaise: Instead of mayo, you can use Greek yogurt or vegan mayonnaise.
  • Coconut aminos: Tamari can be a great substitute for coconut aminos. You can also use Soy sauce, but if you use this, the dish will no longer stay as gluten-free.

Chef's pro tip

If your Brussels sprouts are coming out mushy, it's likely because they're too close together on the baking tray. This causes them to steam rather than roast, messing up that crunchy texture you're aiming for. To get them crispy, make sure you lay the sprouts out in a single, even layer on the baking sheet.

What to serve with keto Brussels sprouts

  • Eggs and grilled protein: With this dish, you can enjoy eggs, grilled chicken or turkey, steak or fish, and seafood. For vegetarians, protein from tofu or tempeh will be great.
  • Keto soups: The creamy mushroom soup goes perfectly with this recipe.
  • Keto casseroles: You can enjoy this low-carb keto side dish with other keto-friendly casseroles such as cheeseburger casserole or keto pesto lasagna.

What can I prepare ahead of time?

  • Prepare the dipping sauce ahead of time and store it in an airtight container in the refrigerator.

Frequently asked questions

Yes! Brussels sprouts are one of the best keto-friendly vegetables. They are low in carbs, with approximately 5 grams of net carbs per 100 grams. In addition, they are high in fiber and packed with nutrients.

Packing too many sprouts onto the baking sheet can block proper heat flow. If you want that perfect crunch, be sure to leave ample room between each sprout on the baking tray.

Usually, bigger Brussels sprouts give a bitter taste and hence are omitted. But if you got larger ones than usual, then you can cut them in half. This ensures that they cook evenly and get crispy.

Yes, stir them halfway through baking. This will help them to roast evenly and form a crispy crust.

The dipping sauce adds an extra layer of flavor to the roasted Brussels sprouts. It's tangy, creamy, and perfectly complements the sprouts. However, you can make this recipe without the sauce.

The recipe provides a creamy mayo-based dip, but you can experiment with other dips like tzatziki, aioli, or spicy salsa. Also, for extra protein, you can use hummus.
