What Ingredients You Will Need
This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples or fresh produce you can find year-round. Here’s a quick rundown of what you’ll need:
- For the Flank Steak:
- 1.5 to 2 pounds (700-900g) flank steak, trimmed (look for a well-marbled cut for juiciness)
- Salt and freshly ground black pepper, to taste
- 2 tablespoons olive oil (choose a good quality extra virgin olive oil like California Olive Ranch for the best flavor)
- For the Chimichurri Sauce:
- 1 cup fresh flat-leaf parsley, packed (roughly chopped)
- 1/2 cup fresh cilantro leaves (optional, but adds a nice brightness)
- 4 garlic cloves, minced (the more, the better for that punch)
- 2 tablespoons fresh oregano leaves, chopped (or 2 teaspoons dried oregano)
- 1/3 cup red wine vinegar (adds the essential tang)
- 3/4 cup olive oil (extra virgin for the best aroma)
- 1 teaspoon red pepper flakes (adjust to your heat preference)
- Salt and pepper, to taste
- For the Grilled Bell Peppers:
- 3 large bell peppers (mix of red, yellow, and orange for color and sweetness)
- 1 tablespoon olive oil
- Salt and pepper, to taste
Pro tip: If you want to swap out the flank steak for a leaner cut, skirt steak works well here too. For a gluten-free variation, make sure your red wine vinegar doesn’t have any additives. In the summertime, I like to swap bell peppers with fresh grilled peaches for a sweet twist reminiscent of the grilled peach and burrata salad I shared last season.
Equipment Needed
- A grill or grill pan – I prefer a charcoal grill for smoky flavor, but a gas grill or indoor grill pan works just fine.
- A food processor or blender – handy for quickly making the chimichurri, but a sharp knife and chopping board work if you’re up for it.
- Mixing bowls – at least two, one for the chimichurri and one for tossing the peppers.
- Tongs – essential for flipping the steak and peppers without losing those precious juices.
- Sharp knife and cutting board – for trimming steak and slicing peppers.
For those on a budget, a sturdy cast-iron skillet can substitute as a grill pan, giving you great searing power indoors. If you don’t have a food processor, I’ve chopped the herbs by hand many times—just takes a bit longer but still delivers that fresh vibrancy. Remember to keep your knives sharp; it makes prep smoother and safer.
Preparation Method

- Make the Chimichurri Sauce (10 minutes): In a food processor, combine parsley, cilantro (if using), garlic, oregano, red wine vinegar, and red pepper flakes. Pulse a few times to roughly chop everything. With the processor running, slowly drizzle in olive oil until the sauce emulsifies but still has texture. Season with salt and pepper to taste. Set aside to let flavors meld.
- Prep the Flank Steak (5 minutes): Pat the flank steak dry with paper towels. Season both sides generously with salt and freshly ground black pepper. Lightly brush with olive oil on both sides to prevent sticking on the grill.
- Prepare the Bell Peppers (5 minutes): Wash and core the bell peppers, then slice them into wide strips. Toss with olive oil, salt, and pepper until evenly coated.
- Preheat the Grill (5-10 minutes): Get your grill hot and ready to go—medium-high heat is best for quick searing and those signature grill marks.
- Grill the Steak (8-12 minutes): Place the flank steak on the grill and cook for about 4-6 minutes per side for medium-rare, depending on thickness. Use tongs to flip once. Look for a nice crust and grill marks. Remove steak and let it rest for 5-10 minutes—this step keeps it juicy.
- Grill the Bell Peppers (6-8 minutes): While the steak rests, add the bell pepper strips to the grill. Cook until tender and slightly charred, turning occasionally for even grilling.
- Slice and Serve: Slice the rested flank steak thinly across the grain to ensure tenderness. Plate with the grilled bell peppers and drizzle a generous spoonful of chimichurri over everything. You can also serve extra sauce on the side for dipping.
Keep an eye on the grill—flank steak cooks fast and you don’t want it tough. Resting the meat is key; I learned the hard way that slicing too soon dries it out. The aroma of garlic and herbs from the chimichurri while grilling is honestly one of those moments that makes you realize food is as much about scent as taste.
Cooking Tips & Techniques
Cooking this chimichurri flank steak is straightforward, but a few insider tips make all the difference:
- Marinate or Not? While chimichurri is great as a marinade, I often toss it on after grilling to keep the herbs fresh and vibrant. If you prefer, marinate the steak for 30 minutes to 2 hours beforehand for deeper flavor.
- Don’t Skip the Rest: Letting the steak rest after grilling redistributes juices, so it stays tender and juicy rather than dry.
- Slice Against the Grain: Flank steak has long muscle fibers; slicing thinly across the grain shortens them and makes each bite easier to chew.
- Grill Peppers at Medium Heat: Too hot and they burn; too cool and they get soggy. Medium heat lets the sugars caramelize without losing that slight crunch.
- Keep Chimichurri Fresh: Make chimichurri just before serving for the brightest flavor. It can be stored in the fridge for up to 3 days but loses its punch over time.
One lesson I learned after a few kitchen mishaps: don’t overload the grill. Crowding the steak and peppers drops the heat and leads to steaming instead of grilling. Patience pays off here. If you want to pair this with something crispy and comforting, try serving alongside crispy smashed potatoes—they soak up the sauce beautifully.
Variations & Adaptations
This chimichurri flank steak recipe is flexible and easy to customize according to what you like or what’s in season:
- Vegetarian Twist: Swap flank steak for large portobello mushrooms marinated in chimichurri and grilled until tender.
- Different Peppers: Try grilling poblano or Anaheim peppers for a smoky, spicy edge instead of sweet bell peppers.
- Spice Level: Add more red pepper flakes or a dash of cayenne to the chimichurri if you want a fiery kick, or omit them completely for a milder sauce.
- Cooking Method: If you don’t have a grill, cook the steak in a hot cast-iron pan, then finish under the broiler to get those charred edges.
- Herb Variations: Add fresh mint or basil to the chimichurri for a different flavor profile. I once tried basil and it gave a fresh, almost sweet note that surprised everyone at the table.
For a quick weeknight spin, pair this dish with the Greek chicken bowls I recently shared, swapping in flank steak and chimichurri for the chicken and tzatziki. It’s a fresh way to keep meals interesting without extra effort.
Serving & Storage Suggestions
Serve the Flavorful Chimichurri Flank Steak with Grilled Bell Peppers warm, straight off the grill, to enjoy the full impact of smoky char and fresh herb sauce. It looks stunning plated with the colorful peppers fanned beside thinly sliced steak drizzled in vibrant green chimichurri.
Pair it with sides like roasted potatoes, grilled corn with chili-lime butter, or even a crisp salad to balance the richness. If you want a lighter option, the grilled peppers themselves can double as a side or even a topping for warm tortillas for a casual taco night.
Leftovers keep well in an airtight container in the refrigerator for up to 3 days. Store steak and chimichurri separately if possible to maintain freshness. To reheat, gently warm the steak in a skillet over medium heat to avoid drying out, and add fresh chimichurri just before serving again. The flavors actually deepen a bit when the steak rests overnight, making it a perfect next-day meal.

Frequently Asked Questions
Can I make chimichurri ahead of time?
Yes, you can prepare chimichurri up to 2-3 days in advance. Store it in an airtight container in the fridge, but for the freshest taste, add any extra olive oil and seasoning just before serving.
What’s the best way to slice flank steak?
Always slice the flank steak thinly against the grain (perpendicular to the muscle fibers). This shortens the fibers and makes the steak more tender and easier to chew.
Can I use other cuts of steak for this recipe?
Yes, skirt steak or hanger steak are great alternatives with similar texture and flavor. Just adjust cooking time based on thickness.
How do I know when the steak is cooked to medium-rare?
Use a meat thermometer to check internal temperature—medium-rare is about 130-135°F (54-57°C). The steak should feel slightly springy when pressed.
Can I make this recipe indoors without a grill?
Absolutely! Use a cast-iron skillet or grill pan on your stovetop. Sear the steak over high heat to get a nice crust, then finish cooking in the pan until desired doneness. Grill the peppers on the pan as well for that smoky char.
