This recipe is a family favorite for Chef Matt Abdoo. Inspired by the meals his mom made, this Italian-marinated flank steak is served with charred peppers, sweet onions, and fresh basil for a simple meal full of flavor. Chef Matt's tip: Slice flank steak against the grain for the most tender bite.
Italian-Marinated Flank Steak with Charred Peppers & Onions
Serves: 4
Prep: 15 minutes + 1–2 hours or overnight to marinate
Cook: 20 minutes
Ingredients
Flank Steak
2 lb flank steak, trimmed
1 cup Italian salad dressing
Kosher salt & black pepper, to taste
Charred Peppers & Onions
1 red bell pepper
1 yellow bell pepper
1 orange bell pepper
1 sweet onion
1 red onion
2 tbsp olive oil
2 tbsp Italian salad dressing
Kosher salt & black pepper, to taste
6 fresh basil leaves
Directions
1. Marinate: Add steak and Italian dressing to a resealable bag. Massage to coat and refrigerate 1–2 hours or overnight.
2. Preheat: Heat grill to high. Clean and lightly oil the grates.
3. Grill vegetables: Cut onions into ½-inch rounds. Drizzle with oil and season with salt and pepper. Grill about 5 minutes without moving until charred. Grill whole peppers, turning occasionally, until blistered on all sides.
4. Finish vegetables: Slice peppers into strips and separate onions into rings. Toss with 2 tbsp Italian dressing, salt, pepper, and fresh basil.
5. Grill steak: Remove steak from marinade and let excess drip off. Season with salt and pepper. Grill 2 minutes, rotate 90°, and cook 2 more minutes. Flip and repeat for about 8 minutes total.
6. Check temperature: For medium-rare, cook to 130°F. If needed, move to a cooler area, close the lid, and cook in 2-minute intervals until desired doneness.
7. Rest & serve: Rest steak 5 minutes, then slice against the grain. Drizzle with Italian dressing and serve with the charred peppers and onions.
