One of my favorite weeknight dinners is this roasted beef with bell peppers, and I love how it comes together in just about an hour. The beautiful thing about this dish is how simple it is to prepare, yet it feels fancy enough for company. I use a quality beef sirloin steak as the star, paired with colorful bell peppers that are packed with vitamin C to boost immunity. The whole thing roasts together in one pan, which means minimal cleanup and maximum flavor. Fresh thyme and balsamic vinegar add depth without requiring any special ingredients. It's budget friendly, impressive, and honestly one of those recipes I find myself making again and again.

Instructions
- 1
Pat the beef strips dry with paper towels and season generously with salt and black pepper on all sides.
Tip: Dry meat ensures better browning and a flavorful crust.
- 2
Heat 2 tablespoons of olive oil in a large cast-iron skillet over medium-high heat until shimmering.
- 3
Working in batches to avoid crowding, sear the beef strips for 2-3 minutes per side until browned. Transfer to a plate.
Tip: Don't overcrowd the pan; this prevents proper browning and moisture loss.
- 4
Add the remaining tablespoon of olive oil to the skillet, then add the onion and bell peppers. Sauté for 5-6 minutes until softened and lightly caramelized.
Tip: Stir occasionally to ensure even cooking and golden edges.
- 5
Add the minced garlic and fresh thyme to the vegetables, cooking for another minute until fragrant.
- 6
Pour in the beef broth and balsamic vinegar, scraping up any browned bits from the bottom of the pan with a wooden spoon.
Tip: These browned bits add deep flavor to your sauce.
- 7
Mix the cornstarch with 1 tablespoon of water to create a slurry, then stir into the sauce to thicken it slightly.
- 8
Return the beef strips to the skillet along with any accumulated juices. Simmer for 3-4 minutes until the beef is heated through and the sauce coats the ingredients.
Tip: Keep the temperature moderate to maintain tender, juicy beef.
