I used to think Brussels sprouts needed a lot of extra ingredients to taste good. But after experimenting with my air fryer, I realized that a little butter, fresh garlic, and a few simple seasonings are all you really need.

They make a fantastic side dish for weeknight dinners, holiday meals, or even a quick snack when you’re craving something savory.

And the best part? You might actually find yourself reaching for seconds!

Ingredients You’ll Need

Here’s everything I usually use to make these delicious air fryer Brussels sprouts.

Main Ingredients

• 1 pound (450g) fresh Brussels sprouts: Choose firm, bright green sprouts for the best results.

How to Make Air Fryer Brussels Sprouts in Garlic Butter

This recipe is incredibly simple, even if you’re not someone who cooks vegetables very often.

Step 1: Prepare the Brussels Sprouts

Start by washing the Brussels sprouts under cool running water. Pat them completely dry using a clean kitchen towel.

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

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

My tip: Try to choose Brussels sprouts that are roughly the same size. This helps them cook at the same speed.

Step 2: Season the Sprouts

Place the halved Brussels sprouts in a large mixing bowl.

Add the olive oil, salt, black pepper, garlic powder, and paprika. Toss everything together until the sprouts are evenly coated.

Make sure the cut sides get a little oil because those are the parts that develop that delicious golden-brown color.

Step 3: Preheat the Air Fryer

Preheat your air fryer to 375°F (190°C) for approximately 3 minutes, if your model requires preheating.

Arrange the Brussels sprouts in the air fryer basket in a single layer, preferably with the cut sides facing down.

Avoid overcrowding the basket. If necessary, cook them in two batches.

Step 4: Air Fry Until Crispy

Cook the Brussels sprouts at 375°F (190°C) for approximately 12–15 minutes.

Shake the basket or turn the sprouts halfway through cooking.

Keep an eye on them toward the end because cooking times can vary depending on the size of your sprouts and your air fryer model.

You’re looking for tender centers, beautifully browned edges, and slightly crispy outer leaves.

If you prefer extra-crispy Brussels sprouts, add another 2–3 minutes.

Step 5: Make the Garlic Butter

While the Brussels sprouts are cooking, prepare the garlic butter.

Melt the butter in a small saucepan over low heat.

Add the minced garlic and cook for approximately 30–45 seconds, stirring frequently.

Be careful not to burn the garlic. Burnt garlic can become bitter, and we definitely don’t want that!

Once fragrant, remove the saucepan from the heat.

Step 6: Toss Everything Together

Transfer the hot, crispy Brussels sprouts to a large mixing bowl.

Pour the warm garlic butter over them and toss gently until every piece is coated.

If you’re using Parmesan cheese, lemon juice, or fresh parsley, add them now.

Give everything one final toss and serve immediately.

Honestly, the smell of fresh garlic butter mixed with roasted Brussels sprouts is enough to make everyone curious about what’s cooking!

Tips for the Best Air Fryer Brussels Sprouts

A few small tricks can make a big difference in how your Brussels sprouts turn out.

1. Dry Them Before Cooking

After washing, make sure the Brussels sprouts are completely dry. Excess moisture can prevent them from browning properly.

2. Don’t Overcrowd the Basket

This is probably the most important tip. Brussels sprouts need enough space for hot air to circulate around them.

If the basket is too crowded, they’ll steam instead of becoming crispy.

3. Place the Cut Sides Down

Whenever possible, arrange the cut sides facing down against the air fryer basket. This helps create beautifully caramelized surfaces.

4. Add Garlic Butter After Air Frying

I recommend adding the garlic butter after cooking rather than before. Fresh garlic can burn during air frying, especially at higher temperatures.

Adding it afterward gives you that lovely garlic flavor without bitterness.

5. Adjust the Cooking Time

Smaller Brussels sprouts may cook in 10–12 minutes, while larger ones might need 15–18 minutes.

Check them regularly and adjust as needed.

6. Don’t Skip the Final Seasoning

Taste the sprouts before serving. Sometimes a little extra salt, freshly ground pepper, or lemon juice is all they need.

What to Serve with Garlic Butter Brussels Sprouts

These crispy Brussels sprouts are incredibly versatile. They’re delicious enough to enjoy on their own, but they also make an excellent side dish.

Here are some of my favorite serving ideas:

• Roasted chicken: Pair them with juicy roasted chicken for an easy family dinner.
• Grilled steak: The buttery garlic flavor complements a perfectly cooked steak.
• Baked salmon: Serve alongside salmon for a delicious and balanced meal.
• Mashed potatoes: A comforting combination that’s perfect for Sunday dinner.
• Garlic butter shrimp: Double up on the garlic butter goodness!
• Rice or quinoa bowls: Add the sprouts to a grain bowl with your favorite protein.
• Holiday meals: They’re a wonderful addition to Thanksgiving, Christmas, or other special occasions.

You can also serve them as an appetizer with a creamy garlic dip or ranch dressing.

Recipe Variations to Try

One of the reasons I love this recipe is how easy it is to change the flavor.

Here are a few variations worth trying:

1. Parmesan Garlic Brussels Sprouts

Add 2 tablespoons of freshly grated Parmesan after air frying. The cheese adds a salty, nutty flavor that tastes amazing with garlic butter.

2. Spicy Garlic Butter Brussels Sprouts

Mix in a pinch of red pepper flakes or cayenne pepper for a little heat.

3. Lemon Garlic Brussels Sprouts

Add fresh lemon juice and a little lemon zest before serving. The citrus brightens the rich butter flavor.

4. Honey Garlic Brussels Sprouts

Stir 1 teaspoon of honey into the melted garlic butter for a slightly sweet and savory combination.

5. Bacon Garlic Brussels Sprouts

Add cooked, crispy bacon pieces before serving. The smoky, salty bacon pairs beautifully with the caramelized vegetables.

How to Store and Reheat Leftovers

If you happen to have leftovers, don’t worry! These Brussels sprouts are easy to store and reheat.

Refrigerator: Allow the sprouts to cool, then transfer them to an airtight container. Store in the refrigerator for up to 3–4 days.

Freezer: You can freeze cooked Brussels sprouts in a freezer-safe container for approximately 2–3 months. However, keep in mind that their texture may become softer after thawing.

Air fryer reheating: Reheat refrigerated Brussels sprouts at 350°F (175°C) for approximately 3–5 minutes, or until warmed through.

Microwave reheating: You can microwave them for 30–60 seconds, although they won’t be as crispy.

My personal recommendation is to use the air fryer again. It brings back some of that lovely crispiness!

Frequently Asked Questions (FAQs)

1. How long do Brussels sprouts take in the air fryer?

Brussels sprouts generally take around 12–15 minutes at 375°F (190°C). However, larger sprouts may need a few additional minutes. Shake the basket halfway through cooking to help them brown evenly.

2. Why are my air fryer Brussels sprouts not crispy?

The most common reasons are excess moisture, overcrowding, or using too much oil. Make sure the sprouts are completely dry before cooking and arrange them in a single layer. Cooking them in batches can also help achieve crispier results.

3. Can I use frozen Brussels sprouts?

Yes! You can use frozen Brussels sprouts, although they may not become quite as crispy as fresh ones. Cook them directly from frozen, preferably without overcrowding the basket. Allow approximately 15–20 minutes at 375°F (190°C), checking for tenderness and browning. Add the garlic butter after cooking.

4. Can I make garlic butter Brussels sprouts without Parmesan?

Absolutely! Parmesan is completely optional. The combination of butter, fresh garlic, and seasonings already provides plenty of flavor. You can also substitute nutritional yeast if you want a cheesy flavor without dairy cheese.

5. Can I prepare Brussels sprouts ahead of time?

Yes! You can wash, trim, and halve the Brussels sprouts up to 1–2 days ahead. Store them in an airtight container in the refrigerator. When you’re ready to cook, season them and air fry as directed. For the best texture, prepare the garlic butter fresh before serving.
