Garlic Butter Air Fryer Steak Bites

Jump to Recipe

Steak bites, but make them fast — this is diced sirloin marinated for a few minutes, air-fried until the edges crisp up, then tossed in a garlic butter sauce that pools into every piece. It’s built for anyone who wants a full steak dinner without pulling out a skillet (or babysitting a grill). Good for a weeknight, and honestly good for anyone still getting comfortable cooking beef.

This is a fifteen-minutes-start-to-finish kind of dinner, which makes it an easy pick for a Tuesday or a lazy Sunday when you don’t want to think too hard about what’s for dinner. The air fryer does the heavy lifting — you’re not standing over a pan flipping pieces one at a time. People come back to this one because the garlic butter does most of the flavor work, and it’s genuinely hard to mess up.

What You’ll Love About This Recipe

  • Ready Fast: Marinate, air fry, and toss in garlic butter — the hands-on process is simple and quick.
  • Minimal Cleanup: You need one air fryer basket and one small bowl for the butter.
  • Crispy, Juicy, and Beginner-Friendly: The air fryer creates browned edges without requiring searing skills, and leftovers work well for meal prep.

Ingredients

You’ll need the following ingredients to make this Garlic Butter Air Fryer Steak Bites:

Cubed sirloin, olive oil, salt, pepper, garlic powder, onion powder, and brown sugar.

Ingredient Notes

Sirloin steak: This is the cut I’d actually recommend — enough fat to stay tender without the ribeye price tag. Cut the pieces evenly, about 1-inch cubes, or the smaller ones will overcook before the big ones catch up.

Brown sugar: Just a half teaspoon, but don’t skip it — it helps the outside caramelize a bit in the air fryer instead of just drying out.

Salted butter: Salted, not unsalted, is the move here. There’s already seasoning on the steak, and you want the sauce pulling some of that weight too.

Garlic: Fresh cloves, minced, not the jarred stuff if you can help it — in a sauce this simple, garlic is basically the whole point, so it’s worth doing right.

Parsley: Purely a fresh-flavor-and-color thing. Skip it if you don’t have it and nothing about the dish suffers.

Recipe Variations

Make It Spicy or Herby: Add red pepper flakes to the garlic butter, or stir in chopped rosemary or thyme with the parsley.

Swap the Protein: Use the same method with chicken thigh pieces or shrimp, reducing the cooking time for shrimp.

Serve It as a Bowl: Spoon the steak over rice or mashed potatoes with extra garlic butter, and add lemon juice to cut through the richness.

Recipe Tips and Tricks

Cut the steak pieces as evenly as possible so they finish cooking at the same time, and don’t skip the short marinating time.

Give the pieces room in the basket. Crowding steams the meat instead of crisping it; check doneness a minute or two early because air fryers vary.

Pour the garlic butter over immediately after cooking, while the steak is still hot enough to soak it in.

Frequently Asked Questions

Can I use a different cut of steak?

Absolutely — ribeye or New York strip both work well if that’s what you have. Watch fattier cuts a little closer, since they can smoke more in the air fryer.

How do I know when the steak bites are done?

A meat thermometer is the most reliable method. Pull them around 130-135°F for medium-rare, or cut into the largest piece and check the color.

Can I make the garlic butter ahead of time?

Yes. Mix it up to a day ahead and keep it covered, then give it a quick warm-up before pouring it over the steak.

Prep Time: 10 minutes
Cook Time: 6 minutes
Chill Time: 15 minutes
Total Time: 31 minutes
Servings: 4 servings

Ingredients

  • 16 oz sirloin steak cut into bite-sized pieces
  • 2 teaspoons olive oil
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/4 teaspoon onion powder
  • 1/4 teaspoon garlic powder
  • 1/2 teaspoon brown sugar

For the Garlic Butter

  • 1-2 cloves garlic minced
  • 3 tablespoons salted butter
  • 1 teaspoon parsley chopped

Instructions

  • Cut the sirloin into bite-sized pieces, keeping them roughly the same size so they cook evenly.
  • In a bowl, whisk together the olive oil, salt, pepper, onion powder, garlic powder, and brown sugar.
  • Add the steak pieces to the bowl and toss until evenly coated. Let them sit for 15-20 minutes to soak up the flavor.
  • Preheat the air fryer to 400°F (200°C).
  • Arrange the marinated steak in a single layer in the basket, leaving space between pieces so air can circulate.
  • Air fry for 4-6 minutes, checking for your preferred doneness.
  • While the steak cooks, melt the butter in a microwave-safe bowl, then stir in the minced garlic and parsley.
  • Transfer the cooked steak to a serving plate and pour the garlic butter sauce over the top, tossing to coat.
  • Let it rest for a couple of minutes so the flavors settle in, then serve hot.

Notes

Store leftovers in an airtight container in the fridge for up to 3 days.
Reheat gently in a skillet over medium heat or back in the air fryer for a couple minutes — the microwave can make the steak tough.
Great served over rice, mashed potatoes, or tossed into a salad.
Double the garlic butter if you like extra sauce for dipping or drizzling.
