And here’s the thing. You don’t need a culinary degree, special equipment, or even a trip to a fancy grocery store. Just a hot pan, a handful of real ingredients, and about 35 minutes.
Let’s get into it.

Pro Tips
Getting perfect beef cubes sounds simple, but a few details will take yours from “pretty good” to absolutely memorable.
1. Pat the beef bone dry before seasoning. This is non-negotiable. Moisture is the enemy of a good sear. Use paper towels, press firmly, and don’t skip this step. Wet beef steams instead of searing. You want that deep, golden-brown crust.
2. Don’t crowd the pan. If your cubes are touching, you’re steaming them. Work in two batches if needed. Give each piece its own space, and your patience will pay off big time.
3. Let the pan get seriously hot before you add anything. A screaming-hot cast iron is what gives you that beautiful crust in under 2 minutes per side. If the oil doesn’t shimmer the second it hits the pan, wait longer.
4. Pull the beef out before you make the sauce. Most people leave the beef in and overcook it while deglazing. Rest your cubes on a plate, make the sauce, then toss them back in at the very end. That’s the secret.
5. Use real butter, not a substitute. The sauce is butter-based, and it genuinely cannot be faked. It creates a silky, glossy finish that lighter fats just can’t replicate.
How to Make It
Step 1: Season the Beef
Combine salt, black pepper, garlic powder, onion powder, and smoked paprika in a small bowl.
Pat your beef cubes completely dry with paper towels. Toss them in the spice mix until every piece is evenly coated.
Let them sit at room temperature for 15 minutes. This helps them sear instead of steam.
Step 2: Sear the Beef
Heat your cast iron skillet over high heat. Add olive oil and let it get very hot, about 2 minutes.
Add the beef cubes in a single layer — do NOT stack them. Sear for 2 minutes per side without moving them. You want a deep brown crust on at least two sides.
Work in two batches if your pan isn’t large enough.
Transfer seared cubes to a plate. Don’t cover them — you don’t want to trap the steam.
Step 3: Make the Garlic Butter Sauce
Reduce heat to medium. Add butter to the same pan (all those browned bits left behind are pure flavor — don’t wipe the pan).
Once butter is melted, add minced garlic. Cook for 60 seconds, stirring constantly.
Add Worcestershire sauce, soy sauce, and Dijon mustard. Stir to combine.
Pour in beef broth and stir, scraping up all the browned bits from the bottom. Let it simmer for 2 to 3 minutes until slightly reduced.
Step 4: Finish It Together
Add the beef cubes back into the pan. Toss to coat in the sauce.
Cook for 1 to 2 more minutes, just until the beef is warmed through and glossy with sauce.
Sprinkle with fresh parsley and serve immediately.
Substitutions and Variations
Beef cut options: Sirloin is ideal for this recipe. Chuck works but needs slightly longer cooking to tenderize. Ribeye cubes are absolutely worth the splurge for a special occasion.
No Worcestershire? A splash of balsamic vinegar plus a tiny pinch of sugar gives you a similar deep, tangy flavor.
Spicy version: Add 1/2 tsp cayenne or a teaspoon of red chili flakes when you sauté the garlic.
Mushroom lovers: Slice 8 oz of cremini mushrooms and cook them in the butter after you remove the garlic. They’ll soak up the sauce and make this dish even more filling.
Keto/low-carb: Already perfect as written. Serve over cauliflower mash instead of potatoes.
Dairy-free: Swap butter for ghee or a plant-based butter alternative. The sauce won’t be quite as silky but will still taste great.
Make Ahead Tips
You can season and cube the beef up to 24 hours in advance. Keep it covered in the fridge, then bring it to room temperature for 15 minutes before cooking.
The sauce also keeps well. Make it separately, refrigerate for up to 3 days, and just reheat gently before adding the freshly seared beef.
This makes it a great option for meal prepping a protein that you can pair with different sides throughout the week.

Leftovers and Storage
Refrigerator: Store in an airtight container for up to 3 days. The sauce will thicken as it cools — that’s normal and actually makes it taste even better the next day.
Freezer: Freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating: Warm on the stovetop over low heat, adding a splash of beef broth to loosen the sauce. Avoid the microwave if you can — it tends to make the beef rubbery.
Leftover ideas:
- Chop smaller and use in tacos or wraps
- Add to a bowl with rice and roasted veggies
- Slice thin and serve over pasta
- Toss into a beef fried rice the next morning
FAQ
What’s the best cut of beef for this recipe? Sirloin is the go-to. It’s tender, cooks fast, and doesn’t require braising. If you use chuck, cut smaller cubes and give them an extra 2 to 3 minutes in the pan.
My sauce is too thin. How do I fix it? Let it simmer a minute or two longer before adding the beef back in. You can also mix 1 teaspoon of cornstarch with 2 teaspoons of cold water and stir it into the simmering sauce.
Can I use a regular skillet instead of cast iron? Yes, a stainless steel pan works well too. Just make sure it’s fully preheated. Non-stick pans aren’t ideal here because they don’t get hot enough for a good sear.
How do I know when the beef is done? For medium, the internal temperature should hit 145°F (63°C). Visually, a good sear and 2 to 3 minutes total cook time will get you there. Don’t slice to check — you’ll lose all the juices.
Can I double the recipe? Yes, but still cook the beef in batches. Doubling the pan load defeats the whole purpose of the high-heat sear.
What if I don’t have Dijon mustard? Regular yellow mustard works in a pinch. The flavor will be slightly sharper but still delicious.
