Ingredients
For the Steak Bites
- Steak (sirloin or tenderloin), cut into bite-sized cubes
- 2 tablespoons butter
- 1 tablespoon olive oil
- Salt and black pepper, to taste
- 1 teaspoon garlic powder or minced garlic
- 1 cup heavy cream
- 1 cup beef broth
- 1 tablespoon Dijon mustard (optional, adds depth)
- Fresh parsley, chopped (for garnish)
For the Mashed Potatoes
- 3–4 medium potatoes, peeled and chopped
- 2 tablespoons butter
- ¼ cup milk or cream
- Salt and black pepper, to taste
Kitchen Tools Needed
- Large skillet – Used to sear the steak bites and build the creamy sauce in the same pan for maximum flavor
- Sharp knife – Ensures clean cuts for evenly sized steak cubes that cook evenly
- Cutting board – Provides a safe, stable surface for prepping steak and potatoes
- Medium pot – Used to boil the potatoes until fork-tender
- Potato masher – Helps create smooth, fluffy mashed potatoes
- Wooden spoon or spatula – For stirring the sauce without scratching the pan
Step-by-Step Instructions
1. Prepare the Steak
Pat the steak cubes dry with a paper towel. Season generously with salt, black pepper, and garlic powder. Dry steak helps achieve a good sear.
2. Sear the Steak Bites
Heat olive oil and butter in a large skillet over high heat. Once hot, add the steak cubes in a single layer.
Sear for 2–3 minutes per side until browned. Do not overcrowd the pan. Remove steak from the skillet and set aside.
3. Make the Creamy Sauce
Reduce heat to medium. In the same skillet, add garlic (if using fresh), beef broth, heavy cream, and Dijon mustard.
Simmer for 3–4 minutes, stirring occasionally, until the sauce thickens slightly.
4. Combine Steak and Sauce
Return the steak bites to the skillet and gently toss to coat them in the creamy sauce. Simmer for 1–2 minutes until heated through.
5. Cook the Mashed Potatoes
Boil potatoes in salted water until fork-tender, about 15–20 minutes. Drain well.
Mash with butter, milk or cream, salt, and pepper until smooth and creamy.
6. Serve
Spoon mashed potatoes onto plates. Top with steak bites and generously drizzle with creamy sauce. Garnish with fresh parsley.
