Keto Lemon Garlic Butter Steak Bites

Featured in: Weeknight Dinners

Succulent sirloin steak cubes are generously seasoned with smoked paprika, salt, and pepper before being seared to golden perfection in hot olive oil. The caramelized exteriors give way to tender, juicy interiors that are then tossed in a vibrant lemon garlic butter sauce infused with fresh parsley and citrus zest. Alongside, Brussels sprouts roast until their edges caramelize and crisp, creating a naturally sweet and nutty contrast to the rich, tangy steak. This satisfying combination delivers bold flavors while keeping carbohydrates low, making it perfect for keto lifestyles without sacrificing taste or texture.

Instructions

Step 1
Preheat the oven to 425°F (220°C).
Step 2
Toss Brussels sprouts with olive oil, salt, and pepper. Spread on a baking sheet, cut side down. Roast for 20–25 minutes, flipping once halfway, until golden and crisped on the edges.
Step 3
While sprouts roast, season steak cubes with salt, pepper, and smoked paprika.
Step 4
Heat 2 tbsp olive oil in a large skillet over high heat. Add steak cubes in a single layer (work in batches if necessary); sear 2–3 minutes per side until browned and cooked to desired doneness. Remove steak bites to a plate and tent with foil.
Step 5
Lower the heat to medium. In the same skillet, melt butter. Add minced garlic and sauté for 30 seconds until fragrant. Stir in lemon zest and juice; cook for 1 minute.
Step 6
Return steak bites to the skillet, tossing to coat in lemon garlic butter. Sprinkle with chopped parsley.
Step 7
Serve steak bites with roasted Brussels sprouts on the side.

Zusatztipps für die Zubereitung

To achieve the best sear, ensure your skillet is very hot before adding the steak and avoid overcrowding the pan; cooking in batches prevents the meat from steaming. Always pat the steak dry with paper towels before seasoning to help form a beautiful crust.

Varianten und Anpassungen

You can easily swap sirloin for ribeye or New York strip for a more marbled, rich flavor. For those who enjoy a bit of heat, adding a pinch of crushed red pepper to the lemon garlic butter sauce provides a wonderful spicy kick.

Serviervorschläge

This dish pairs beautifully with a dry white wine such as Chardonnay or Sauvignon Blanc. For a more filling meal, consider serving the steak bites alongside a side of cauliflower mash or a fresh green salad with a light vinaigrette.

Recipe FAQ

What cut of steak works best for steak bites?

Sirloin is an excellent choice for steak bites due to its balance of tenderness and flavor. However, you can also use ribeye or New York strip for a more luxurious texture. The key is cutting the steak into uniform 1-inch cubes to ensure even cooking and consistent searing.

How do I know when the steak bites are done?

Steak bites typically reach medium-rare after 2-3 minutes per side. For medium doneness, cook for an additional minute per side. The best method is using an instant-read thermometer—130°F for medium-rare, 140°F for medium. Remember that the steak will continue cooking slightly when removed from heat.

Can I make the lemon garlic butter sauce ahead of time?

While the sauce comes together quickly in the pan, you can prepare a compound butter in advance by mixing softened butter with minced garlic, lemon zest, and parsley. Roll it into a log, refrigerate, and slice off portions to melt over hot steak bites for instant flavor.

What other vegetables pair well with this dish?

Alongside Brussels sprouts, consider roasted asparagus, cauliflower, broccoli, or green beans. Root vegetables like radishes or turnips also work well for keto diets. The key is choosing vegetables that roast beautifully and complement the bright lemon butter flavors.

How can I add more spice to this dish?

Add crushed red pepper flakes to the butter sauce for gentle heat, or incorporate cayenne pepper into the steak seasoning blend. You could also use a spicy finish like harissa or chili oil. For smoky heat, chipotle powder in the rub pairs wonderfully with the lemon garlic notes.

Is this meal freezer-friendly?

The cooked steak bites can be frozen for up to 3 months, though the texture may be slightly less tender upon reheating. Freeze components separately—steak bites, sauce, and roasted sprouts—in airtight containers. Reheat gently in a skillet over medium-low heat to maintain juiciness.
