Tender sirloin bites seared until crusty, tossed in garlic herb butter, and served over a silky parmesan cream sauce — a steakhouse-worthy dinner in under 30 minutes.
1Pat the steak cubes dry with paper towels and toss with salt, pepper, and smoked paprika.
2Heat olive oil in a large skillet over medium-high heat until shimmering. Sear the steak bites in a single layer (work in two batches if needed) for 2–3 minutes per side until deeply browned. Transfer to a plate and cover loosely with foil.
3Reduce heat to medium. Add 2 tbsp butter to the same skillet; once melted, stir in the garlic and thyme and cook 30 seconds until fragrant.
4Pour in the heavy cream, scraping up the browned bits. Simmer 2 minutes until slightly thickened.
5Whisk in the Dijon, then sprinkle in the Parmesan a handful at a time, whisking until smooth. Stir in the red pepper flakes if using. Taste and adjust salt.
6Return the steak bites (and any juices) to the skillet along with the remaining 2 tbsp butter. Toss for 1–2 minutes until the bites are coated and warmed through.
7Spoon over mashed potatoes, rice, or crusty bread and shower with fresh parsley. Serve immediately.
