What Ingredients You Will Need

This recipe leans on fresh, straightforward ingredients that come together to pack serious flavor without fuss. Most are pantry staples or easy to find at your local market.

• For the Chimichurri Sauce:
  • Fresh parsley, finely chopped (about 1 cup packed) – the base of the sauce
  • Fresh cilantro, finely chopped (½ cup) – adds brightness
  • Garlic cloves, minced (3 large) – pungent and essential
  • Red wine vinegar (¼ cup) – gives the tangy kick
  • Extra virgin olive oil (⅓ cup) – brings richness and helps flavors meld
  • Red pepper flakes (¼ tsp) – just a hint of heat
  • Salt and freshly ground black pepper (to taste)
  • Optional: A squeeze of fresh lemon juice for extra zing
• For the Flank Steak:
  • Flank steak, about 1.5 to 2 pounds (680-900 g) – look for well-marbled for juiciness
  • Salt and pepper, for seasoning
  • Olive oil (1 tbsp) – to coat before grilling
• For the Grilled Vegetables:
  • Zucchini, sliced lengthwise (2 medium) – tender yet sturdy for grilling
  • Red bell pepper, cut into large strips (1 large) – adds sweetness and color
  • Red onion, cut into thick wedges (1 medium) – caramelizes beautifully
  • Asparagus spears, trimmed (1 bunch) – quick to grill and adds crunch
  • Olive oil (2 tbsp) – for drizzling
  • Salt and pepper, to taste

Pro tip: I trust Colavita olive oil for its robust flavor, especially in chimichurri. If you can find fresh herbs at a farmers’ market, even better — they really make a difference. For a gluten-free version, this recipe works perfectly as is, no substitutions needed.

Equipment Needed

• Grill or grill pan – a charcoal grill adds smokiness, but a stovetop grill pan works well too.
• Sharp chef’s knife – for chopping herbs and slicing vegetables evenly.
• Mixing bowls – one for the chimichurri sauce, one for marinating the steak.
• Tongs – to flip the steak and vegetables without piercing the meat.
• Cutting board – preferably separate ones for meat and veggies.
• Meat thermometer (optional) – helpful for checking doneness, especially if you’re new to grilling steak.

If you don’t have a grill, a cast-iron skillet is a great alternative for cooking the steak and veggies indoors. Personally, I’ve found that using tongs instead of forks keeps the juices locked in, which makes a noticeable difference.

Preparation Method

1. Make the Chimichurri Sauce (10 minutes): In a medium bowl, combine finely chopped parsley, cilantro, and minced garlic. Add red wine vinegar, olive oil, red pepper flakes, and a pinch of salt and pepper. Stir well to combine. Taste and adjust seasoning, adding lemon juice if desired. Cover and let it sit while you prep the steak and veggies — this lets the flavors meld beautifully.
2. Prep the Flank Steak (5 minutes): Pat the flank steak dry with paper towels. Rub it evenly with olive oil, then season generously with salt and pepper on both sides. Set aside at room temperature for about 10 minutes — this helps it cook more evenly.
3. Prepare the Vegetables (10 minutes): Slice zucchini lengthwise into ¼-inch thick strips, cut the red bell pepper into large strips, wedge the red onion, and trim the asparagus. Toss all vegetables in a bowl with olive oil, salt, and pepper until evenly coated.
4. Preheat the Grill (5 minutes): Heat your grill or grill pan to medium-high heat. You want it hot enough to get nice grill marks but not so hot that the steak burns before cooking through.
5. Grill the Flank Steak (6-8 minutes per side): Place the steak on the grill and cook for about 6-8 minutes per side for medium-rare (internal temp around 130°F/54°C). Use a meat thermometer to check if unsure. Avoid flipping too often to get a nice crust. Once done, transfer to a plate and tent loosely with foil to rest for 5-10 minutes — this step is key for juicy steak.
6. Grill the Vegetables (8-10 minutes): While the steak is resting, grill the vegetables. Arrange them on the grill perpendicular to grates to avoid slipping. Cook until tender and nicely charred, turning occasionally. Asparagus may take less time, so keep an eye on it.
7. Slice and Serve: Slice the flank steak thinly against the grain to maximize tenderness. Spoon generous amounts of chimichurri over the steak slices and arrange alongside the grilled vegetables. Serve immediately.

Note: If your steak is thicker or thinner than 1 inch, adjust grilling time accordingly. And don’t skip resting the steak — I learned that the hard way when my first attempt was dry because I sliced too soon!

Cooking Tips & Techniques

Grilling flank steak can feel intimidating, but a few insider tips make all the difference. First off, seasoning well with salt before grilling pulls out the steak’s natural flavor and helps build that crave-worthy crust. I like to let the steak sit at room temp before grilling so it cooks evenly without cold spots.

For chimichurri, the trick is in the chopping. I recommend hand-chopping herbs finely rather than blitzing them in a food processor. It keeps the texture fresh and rustic — plus, the herbs don’t bruise and turn bitter.

When grilling vegetables, make sure they’re cut uniformly so everything cooks at the same pace. Brush them lightly with oil to prevent sticking, and don’t overcrowd the grill — give each piece some breathing room for better caramelization.

If you’re short on time, grill the steak in advance and reheat gently on the grill or stovetop while cooking the veggies. But honestly, this recipe is quick enough you can do everything fresh in one go.

One last tip: always slice flank steak against the grain. That means cutting perpendicular to the muscle fibers, which makes each bite tender instead of chewy.

Variations & Adaptations

This flavorful chimichurri flank steak is quite versatile, so you can tweak it to suit your tastes or dietary needs.

• Spicy Chimichurri: Add more red pepper flakes or a diced fresh jalapeño to the sauce for a fiery kick.
• Herb Swap: Try swapping cilantro for fresh oregano or basil if parsley isn’t your favorite.
• Vegetable Variations: Swap grilled zucchini and bell peppers for summer corn on the cob, mushrooms, or eggplant. These all grill beautifully.
• Low-Carb or Keto: This recipe naturally fits low-carb diets. Serve the steak and vegetables over a bed of sautéed spinach or cauliflower rice for a fuller meal.
• Dairy-Free and Gluten-Free: No adjustments needed — this is naturally free of dairy and gluten.

Once, I tried adding a splash of smoked paprika to the chimichurri, which gave it a subtle smoky warmth that went surprisingly well with the grilled veggies. Feel free to experiment — this recipe rewards small tweaks.

Serving & Storage Suggestions

Serve this chimichurri flank steak warm off the grill, spooning extra sauce over the top to keep things juicy. I love plating it with a colorful medley of grilled vegetables for a vibrant, rustic presentation. A simple green salad or some crusty bread can round out the meal nicely.

If you have leftovers, store steak and vegetables separately in airtight containers in the fridge. They’ll keep well for 3 to 4 days. Reheat gently in a skillet or oven to avoid drying out the steak.

The chimichurri sauce actually tastes better after resting overnight, so make a little extra and keep it chilled. It’s fantastic as a marinade or condiment for other grilled meats or even roasted potatoes.

This recipe pairs nicely with a dry red wine or a crisp rosé, especially on warm evenings. If you’re looking for a refreshing summer side, you might enjoy pairing this with an easy summer pasta salad or a fresh summer bruschetta appetizer to keep the vibe light and lively.
