What You’ll Need

For the Steak Bites

  • 1.5 lbs sirloin steak (or ribeye), cut into 1-inch cubes
  • 2 tablespoons avocado oil (or any high smoke-point oil)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder

For the Garlic Butter Sauce

  • 4 tablespoons unsalted butter
  • 5 cloves garlic, minced
  • 1 tablespoon fresh rosemary, finely chopped
  • 1 tablespoon fresh thyme leaves
  • 1 tablespoon fresh parsley, chopped (for garnish)
  • 1/2 teaspoon red pepper flakes (optional)
  • Salt and pepper to taste

Tools You’ll Need

  • 12-inch cast iron skillet (highly recommended)
  • Tongs
  • Cutting board and sharp chef’s knife
  • Small bowl for mixing the dry rub
  • Paper towels

Pro Tips

Tip 01

Pat your steak completely dry. This is the single most important step. Moisture on the surface = steaming instead of searing. Dry steak = that gorgeous golden crust. Use paper towels and press firmly.

Tip 02

Don’t overcrowd the pan. Cook in two batches if needed. Steak pieces touching each other will steam, not sear. You want space between each piece for real browning.

Tip 03

Let the pan get screaming hot first. Add the oil only after the cast iron is fully preheated. When a drop of water flicks off immediately, you’re ready.

Tip 04

Add butter at the end. Butter burns at high heat. Sear the steak first in oil, then drop the heat and add butter for the sauce. Best of both worlds.

Tip 05

Don’t skip the rest. Two minutes off heat before serving lets the juices redistribute. Slice too soon and those juices run everywhere.

How to Make Keto Garlic Butter Steak Bites

  1. Pat steak dry with paper towels, then cut into 1-inch cubes.
  2. Season the steak with salt, pepper, smoked paprika, and garlic powder. Toss to coat evenly.
  3. Heat your skillet over high heat for 2 minutes until smoking hot. Add avocado oil.
  4. Sear the steak in a single layer for 1–2 minutes per side. Work in batches. Set aside on a plate.
  5. Reduce heat to medium. Add butter to the same pan and let it melt.
  6. Add garlic, rosemary, and thyme. Stir constantly for about 60 seconds until fragrant.
  7. Return steak bites to the pan. Toss everything together for 30 seconds, coating each piece in the butter sauce.
  8. Taste and adjust salt and pepper. Top with fresh parsley and serve immediately.

Substitutions and Variations

Steak Cuts

  • Ribeye adds more fat and flavor (great for keto)
  • New York strip works perfectly too
  • Tenderloin if you want the most tender bite
  • Flank steak is budget-friendly, just slice against the grain

Butter Alternatives

  • Ghee works great and has a higher smoke point
  • Dairy-free butter if you’re sensitive to dairy

Herb Swaps

  • No fresh herbs? Dried work too. Use 1 tsp dried rosemary and 1/2 tsp dried thyme.
  • Oregano or tarragon make great flavor variations

Flavor Variations

  • Spicy version: Double the red pepper flakes, add a pinch of cayenne
  • Lemon herb: Squeeze half a lemon over the finished dish
  • Mushroom version: Add sliced cremini mushrooms to the butter sauce

Make Ahead Tips

Good news: the prep work here is almost nothing.

  • Season and cube the steak up to 24 hours ahead. Store covered in the fridge.
  • Mince the garlic and chop herbs in advance. Keep refrigerated in a small bowl.
  • The actual cook time is so fast that making this fully ahead isn’t necessary. This is genuinely a same-day meal that won’t stress you out.

What to Serve With Keto Steak Bites

Keep it keto-friendly:

  • Cauliflower mash to soak up all that garlic butter
  • Roasted asparagus or broccoli tossed in olive oil
  • Zucchini noodles dressed lightly
  • A simple arugula salad with lemon and olive oil
  • Sauteed spinach with garlic (the butter sauce pairs perfectly)

Leftovers and Storage

Storing

  • Transfer cooled steak bites to an airtight container
  • Refrigerate for up to 3 days

Reheating

  • Best method: Warm in a skillet over medium heat with a tiny splash of water or beef broth. 2–3 minutes tops.
  • Avoid the microwave if you can. It’ll overcook the steak and make it rubbery.
  • Cold steak bites also taste amazing sliced thin over a salad.

Freezing

  • Can be frozen for up to 2 months
  • Thaw overnight in the fridge before reheating

FAQ

Can I use frozen steak?

You can, but thaw it fully first. Frozen steak will drop the pan temperature and make searing nearly impossible. Take it out of the freezer the night before.

What’s the best pan to use?

Cast iron, no contest. It holds heat better than any other pan, which means a better sear. Stainless steel is a solid backup. Avoid nonstick for this recipe.

My steak bites are tough. What went wrong?

Two common culprits: overcooked, or sliced the wrong way against the grain. For steak bites, medium-rare to medium (130–145°F) is the sweet spot. Cook them past that and toughness follows.

Is this recipe truly keto?

Yes. At roughly 1.5g net carbs per serving, this fits comfortably within standard keto macros. The only carbs come from garlic and herbs.

Can I make this in a regular skillet?

Yes. A heavy stainless steel pan works well. Nonstick will technically work but won’t give you that deep golden crust. The crust is kind of the whole point.

How do I know when the steak is done?

Visually: you want deep brown edges and a slightly pink center for medium-rare. With a meat thermometer: 130°F for medium-rare, 140–145°F for medium.

Wrapping Up

This is the recipe you’ll keep coming back to.

It’s fast. It’s cheap compared to dining out. It tastes like you actually know what you’re doing in the kitchen. And it fits your keto lifestyle without feeling like a compromise.

The garlic butter sauce alone is worth making this for. It coats every piece of steak and smells absolutely absurd in the best way.
