A delightful twist on a classic sirloin dish, featuring a creamy garlic sauce and tender steak.
Cut the sirloin steak into serving-sized pieces.
Cutting the steak into even pieces ensures uniform cooking.
In a mixing bowl, combine the flour, paprika, salt, and pepper. Dredge the steak pieces in the mixture.
Shake off any excess flour to prevent clumping during cooking.
Heat oil in a skillet over medium-high heat. Sear the steak pieces on one side until browned, then flip and sear the other side.
Ensure the skillet is hot before adding the steak to achieve a good sear.
Add the chopped onion and minced garlic to the skillet. Cook until fragrant.
Stir frequently to prevent the garlic from burning.
Mix the soy sauce, brown sugar, and mustard in a small bowl. Pour the mixture into the skillet and stir.
Deglaze the skillet with the sauce to incorporate all the flavors.
Cover the skillet and let the steak simmer for 10 minutes.
Check occasionally to ensure the sauce doesn't reduce too much.
Stir in the sour cream and cook until heated through.
Avoid boiling the sour cream to prevent curdling.
Serve the steak and sauce over cooked rice.
Garnish with fresh parsley for a pop of color.
