For the Brussels sprouts

• 2 tablespoons melted butter

• 1 tablespoon olive oil

• 4 garlic cloves, minced

• ½ teaspoon salt

• ½ teaspoon black pepper

• ½ teaspoon paprika

• ¼ teaspoon onion powder

How to Make Air Fryer Brussels Sprouts in Garlic Butter

Step 1: Prepare the Brussels sprouts

Start by washing the Brussels sprouts thoroughly under cool running water.

Trim off the tough ends and remove any yellow or damaged outer leaves.

Cut each Brussels sprout in half lengthwise. If you have particularly large ones, cut them into quarters so they cook evenly.

Pat them completely dry with a clean kitchen towel.

This step is important because removing excess moisture helps the Brussels sprouts develop those lovely crispy edges.

Step 2: Prepare the seasoning mixture

In a large mixing bowl, combine the melted butter, olive oil, minced garlic, salt, black pepper, paprika, and onion powder.

Whisk everything together until well combined.

Add the prepared Brussels sprouts and toss gently until every piece is coated with the garlic butter seasoning.

Make sure the seasoning reaches the cut sides because those surfaces become especially delicious when they turn golden in the air fryer.

Step 3: Preheat the air fryer

Preheat your air fryer to 375°F (190°C) for approximately 3–5 minutes, following your appliance’s instructions.

Lightly grease the air fryer basket if needed.

Arrange the Brussels sprouts in a single layer, placing as many cut sides down as possible.

Avoid overcrowding the basket. If necessary, cook in batches so the hot air can circulate properly.

Step 4: Air fry until crispy

Cook the Brussels sprouts at 375°F (190°C) for approximately 12–16 minutes.

Shake the basket halfway through cooking to help them brown evenly.

Keep an eye on the smaller pieces because they may cook faster.

The outside should become beautifully golden and crispy, while the inside should be tender enough to pierce easily with a fork.

Step 5: Make the garlic butter topping

While the Brussels sprouts are cooking, prepare the finishing sauce.

Melt 2 tablespoons of butter in a small saucepan over low heat.

Add the finely minced garlic and cook for approximately 30–45 seconds until fragrant.

Be careful not to brown or burn the garlic because it can become bitter.

Remove from the heat and stir in the lemon juice, Parmesan cheese, and chopped parsley.

Step 6: Toss everything together

Transfer the hot Brussels sprouts into a serving bowl.

Pour the prepared garlic butter mixture over them and toss gently until everything is coated.

Sprinkle with a little extra Parmesan cheese and red pepper flakes if desired.

Serve immediately while the Brussels sprouts are warm, buttery, and crispy.

Tips for the Best Crispy Brussels Sprouts

A few little tricks can make a big difference in the final result.

• Dry them properly: Wet Brussels sprouts tend to steam instead of crisp.

• Cut them evenly: Similar-sized pieces help everything cook at the same rate.

• Don’t overcrowd the basket: Air circulation is essential for crispy edges.

• Place cut sides down: This encourages better browning.

• Use fresh garlic: Freshly minced garlic gives the best flavor.

• Add finishing butter carefully: Tossing the cooked sprouts in garlic butter keeps the topping flavorful.

• Serve immediately: Brussels sprouts are at their crispiest straight from the air fryer.

4. Lemon Parmesan Brussels Sprouts

5. Bacon Garlic Brussels Sprouts

Toss the cooked Brussels sprouts with crispy bacon pieces for a smoky and savory twist.

How to Store and Reheat Leftovers

If you have leftover Brussels sprouts, don’t worry! They can easily be saved for another meal.

Refrigerator: Allow them to cool and transfer them to an airtight container. Refrigerate for up to 3–4 days.

Freezer: Freezing is possible, but the Brussels sprouts may become softer after thawing. For the best texture, enjoy them fresh or refrigerated.

Air fryer reheating: Place leftovers in the air fryer at 350°F (175°C) for approximately 3–5 minutes until heated through.

Microwave: You can microwave individual portions, although the texture will be softer.

Frequently Asked Questions

1. Why are my Brussels sprouts not crispy?

Excess moisture, overcrowding, and insufficient air circulation are common reasons. Dry the Brussels sprouts thoroughly and arrange them in a single layer.

2. Can I use frozen Brussels sprouts?

Yes! Frozen Brussels sprouts can be used, but they generally won’t become as crispy as fresh ones. Cook them from frozen, avoid overcrowding, and allow extra cooking time as needed.

3. Do I need to boil Brussels sprouts before air frying?

No. Fresh Brussels sprouts can go directly into the air fryer after washing, trimming, drying, and seasoning.

4. Can I make this recipe without butter?

Absolutely! Replace the butter with additional olive oil or a suitable dairy-free butter alternative.

5. Can I add Parmesan before air frying?

You can, but adding it toward the end or after cooking helps prevent the cheese from burning.

6. How do I prevent garlic from burning?

Use minced garlic in the seasoning mixture sparingly, and add most of the garlic butter sauce after cooking. This gives you plenty of garlic flavor without scorching it.

7. Can I prepare Brussels sprouts ahead of time?

Yes! Wash, trim, and halve them a day ahead. Store them in an airtight container in the refrigerator. For the crispiest results, season just before air frying.
