Garlic Butter Steak Bites and Potatoes (One Pan, 25 Minutes!)
This post may contain affiliate links. Read my disclosure policy.
I made these on a complete whim one Wednesday night with a sirloin steak sitting in the refrigerator and absolutely zero patience for a complicated dinner. I cut the steak into cubes, seared them hard in a screaming hot cast iron pan, tossed in some baby potatoes and a ridiculous amount of garlic butter, and had the best thing I had eaten all week on the table in about twenty-five minutes. Garlic butter steak bites and potatoes has been in my regular dinner rotation ever since. The steak pieces develop a dark, caramelized crust in minutes, the potatoes get crispy and golden, and the whole pan gets bathed in garlic herb butter that ties everything together into something that tastes like a steakhouse dinner for a fraction of the price and effort.

The Secret to Perfect Steak Bites
Steak bites live or die by one thing — the sear. A deep, mahogany-brown crust on every side of every piece is what separates good steak bites from extraordinary ones. Three things make the difference: your pan must be screaming hot before the steak goes in, your steak pieces must be completely dry on the surface, and you must not crowd the pan. Overcrowded steak steams instead of searing. Cook in two batches if necessary — the extra few minutes are completely worth it.
What Cut of Steak to Use
- Sirloin — top pick. Excellent flavor, affordable, perfect texture for steak bites
- Ribeye — more marbling, more flavor, most indulgent version
- New York strip — similar to sirloin, slightly more tender
- Flank or skirt steak — works if sliced against the grain into 1-inch pieces
Ingredients You’ll Need
Steak bites
- 1½ lbs sirloin steak, cut into 1-inch cubes — pat completely dry before seasoning
- 1 tsp garlic powder, 1 tsp onion powder, ½ tsp smoked paprika, 1 tsp kosher salt, ½ tsp black pepper
- 1 tbsp olive oil for searing
Potatoes
- 1 lb baby potatoes, halved — Yukon Gold or red, the cut side gets crispy and golden
- 2 tbsp olive oil, ½ tsp salt, ¼ tsp pepper
Garlic butter sauce
- 4 tbsp unsalted butter — generous and necessary
- 6 cloves garlic, minced — do not hold back
- 1 tbsp soy sauce — the umami secret that deepens the sauce dramatically
- 1 tbsp Worcestershire sauce — adds depth and complexity
- Fresh rosemary and thyme sprigs, fresh parsley for garnish
How to Make Garlic Butter Steak Bites and Potatoes
Step 1: Cook the potatoes first
Heat 2 tbsp olive oil in a large cast iron skillet over medium-high. Add potatoes cut-side down. Season with salt and pepper. Cook undisturbed 4 to 5 minutes until deeply golden. Flip and cook another 3 to 4 minutes. Remove to a plate — they do not need to be fully cooked through yet.
Step 2: Sear the steak in batches
Pat steak cubes completely dry. Season on all sides. Increase heat to HIGH. Add olive oil and let it just begin to smoke. Add steak in ONE single layer — work in batches, never crowd the pan. Sear 1 to 2 minutes per side until a deep dark brown crust forms. Remove to plate. Repeat with remaining steak.
Step 3: Make the garlic butter sauce
Reduce heat to medium. Add butter to the same pan. Once melted, add garlic, rosemary, and thyme. Cook stirring 60 to 90 seconds until fragrant. Add soy sauce and Worcestershire sauce. Return steak and potatoes to the pan and toss everything in the garlic butter. Cook 1 minute until glistening. Remove herb sprigs.
Step 4: Serve immediately
Serve immediately from the cast iron skillet. Scatter generously with fresh parsley and extra black pepper. Have crusty bread ready for the garlic butter in the pan — it is too good to waste.
Tips for the Best Steak Bites
- Always pat the steak completely dry — surface moisture prevents searing and causes steaming
- Use a cast iron skillet — holds heat better than any other pan for the deepest sear
- Get the pan genuinely hot before the steak goes in
- Cook in batches — one layer with space between pieces, always
- Do not move the steak during the sear — let it sit undisturbed until it releases naturally
Variations
- Add mushrooms — cremini mushrooms cooked in the garlic butter add earthy richness
- Add asparagus — trimmed spears in the last 3 minutes, coated in garlic butter
- Make it spicy — add ½ tsp red pepper flakes to the garlic butter
- Add parmesan — grate fresh parmesan over the top just before serving
- Lemon butter — add a squeeze of lemon to the garlic butter for brightness
What to Serve With
- Crusty bread — mandatory, for the garlic butter in the pan
- Simple green salad — fresh and light to balance the richness
- Roasted asparagus or green beans — simple sides that soak up the butter
- Steamed broccoli — easy side that works beautifully
Frequently Asked Questions
What is the best doneness for steak bites?
Medium-rare to medium is ideal. At 1-inch cubes, 1 minute per side at high heat gives you medium-rare, 1.5 to 2 minutes gives you medium. The steak continues cooking slightly in the butter sauce so err on the side of undercooking during the sear.
Why is my steak steaming instead of searing?
Three possible reasons: the pan was not hot enough, the steak was wet rather than dry, or the pan was overcrowded. All three cause steaming. Make sure the pan is properly preheated, the steak is completely dry, and cook in batches.
Can I use a different pan?
A large stainless steel skillet also works well. Avoid nonstick pans — they cannot safely reach the high temperatures needed for proper searing.
Can I prep this ahead?
You can cut and season the steak and halve the potatoes ahead. But cook everything fresh — the dish takes only 25 minutes and the quality difference between fresh and reheated is significant.
