What Ingredients You Will Need

This recipe calls for straightforward, wholesome ingredients that come together to create bold flavor and satisfying textures without any fuss. Most are pantry staples or fresh herbs you can find year-round, and there’s some flexibility if you want to swap or adjust.

• Flank Steak (1.5 to 2 pounds / 700-900 grams) – Choose a good-quality cut with nice marbling for juiciness; grass-fed works great if you prefer.
• Fresh Parsley (1 cup, packed, finely chopped) – The backbone of chimichurri, providing that bright, grassy flavor.
• Fresh Cilantro (1/2 cup, chopped) – Adds a gentle citrusy lift; optional if you’re not a fan, but recommended.
• Garlic (4 cloves, minced) – Gives punch and warmth to the sauce.
• Red Wine Vinegar (3 tablespoons) – Brings acidity and balance; I like Colavita brand for consistent quality.
• Olive Oil (1/2 cup) – Use extra virgin for the best flavor and richness.
• Red Pepper Flakes (1/2 teaspoon) – Just a hint of heat to keep things interesting.
• Salt and Black Pepper (to taste) – Season to balance the flavors.
• Vegetables for Grilling:
• Zucchini (2 medium, sliced lengthwise)
• Red Bell Peppers (2, seeded and quartered)
• Red Onion (1 large, cut into thick slices)
• Cherry Tomatoes (1 cup, skewered or in a grill basket)
• Lemon Juice (optional splash for finishing) – Adds a fresh zing if you want a little extra brightness.

If you want to experiment, almond flour can be used to dust the steak lightly before grilling if you prefer a slight crust. For dairy-free or vegan chimichurri variants, just skip the steak and serve over grilled portobello mushrooms or cauliflower steaks for a hearty twist.

Equipment Needed

• Grill or Grill Pan: Essential for that authentic char and smoky flavor. A gas or charcoal grill works beautifully, but if you’re indoors, a heavy-duty grill pan does the trick. I’ve used both with great results.
• Mixing Bowls: For whisking together the chimichurri ingredients and tossing vegetables.
• Sharp Knife and Cutting Board: For prepping the steak and vegetables cleanly.
• Meat Thermometer: Optional but handy to check doneness without cutting into the steak and losing juices.
• Skewers or Grill Basket: Useful for smaller veggies like cherry tomatoes to keep them from falling through the grates.
• Tongs: For easy flipping of steak and vegetables without piercing the meat.

If you don’t have a grill thermometer, no worries — I’ll share cues on when your steak is ready. For budget-friendly grilling, a cast iron skillet can mimic some of the char effects indoors, though it won’t replicate the smoky aroma fully. Keeping your tools clean and well-oiled will make grilling smoother and prevent sticking.

Preparation Method

1. Make the Chimichurri Sauce: In a medium bowl, combine 1 cup finely chopped parsley, 1/2 cup chopped cilantro, 4 minced garlic cloves, 3 tablespoons red wine vinegar, 1/2 cup extra virgin olive oil, 1/2 teaspoon red pepper flakes, and salt and black pepper to taste. Stir well until emulsified. Set aside at room temperature to let flavors meld while you prep the steak and veggies. (About 10 minutes)
2. Prepare the Flank Steak: Pat the steak dry with paper towels. Season generously on both sides with salt and pepper. Place the steak in a shallow dish or zip-top bag and pour half of the chimichurri over it, turning to coat thoroughly. Cover and refrigerate for at least 30 minutes — no more than 2 hours to keep the texture tender.
3. Prep the Vegetables: While the steak marinates, slice zucchini lengthwise into 1/4-inch thick strips, quarter the bell peppers, and cut the red onion into thick slices. Toss all vegetables in a bit of olive oil and sprinkle salt and pepper evenly. Skewer cherry tomatoes or place them in a grill basket to avoid losing them on the grates.
4. Preheat the Grill: Heat your grill or grill pan to medium-high heat (about 400-450°F / 200-230°C). Clean and oil the grates to prevent sticking. This is key for those beautiful grill marks and easy flipping.
5. Grill the Vegetables: Place the prepared veggies on the grill first since they take a bit longer. Grill zucchini, peppers, and onions for 4-6 minutes per side until tender with nice char marks. Cherry tomatoes will take about 3-4 minutes, turning occasionally. Remove veggies and keep warm.
6. Grill the Flank Steak: Place the marinated steak on the hot grill. Cook for about 4-5 minutes per side for medium-rare (internal temp ~130°F / 54°C), or longer if you prefer. Use tongs to flip once — no poking! Let the steak rest for 5-10 minutes after grilling to lock in juices.
7. Serve: Slice the flank steak thinly against the grain for tenderness. Spoon the reserved chimichurri sauce over the top, and plate alongside the grilled vegetables. Add a splash of lemon juice if you like a little extra zing before serving.

Pro tip: If your steak feels tough, try letting it rest longer or slice even thinner. The chimichurri sauce’s acidity helps break down fibers, but cutting against the grain is the secret weapon here. Also, keep an eye on the grill temperature — too hot and you risk burning the outside while the inside stays undercooked.

Cooking Tips & Techniques

Chimichurri flare aside, making this flank steak and grilled vegetable combo just right takes a few tricks I picked up over time. First, don’t skip the resting step after grilling. I’ve made the mistake of slicing too soon, and it’s like losing all that juicy goodness instantly. Patience pays off.

When marinating, keep it under two hours. Longer than that, and the vinegar can start to “cook” the meat and make it mushy. Also, trimming excess fat from the flank steak helps prevent flare-ups on the grill, which can char the meat unevenly.

For the vegetables, slice them uniformly so they cook evenly. Zucchini and peppers are forgiving, but onions can sneak from crisp to burnt fast if left unattended. I usually multitask by grilling veggies first, then steak, so I can adjust heat and timing easily.

Don’t be shy about seasoning generously — chimichurri and salt are your best friends here. And, if you want a smoky punch, add a small handful of soaked wood chips to your charcoal grill or use a smoking box on gas grills.

Variations & Adaptations

This recipe is pretty flexible and can be tweaked to suit different diets or tastes without losing its essence. Here are some ideas I’ve tried or recommend:

• Protein Swap: Substitute flank steak with skirt steak or sirloin for a slightly different texture but similar flavor. For a poultry twist, try the chimichurri on grilled chicken breasts, like in this marinated grilled chicken breast recipe.
• Vegetarian Option: Grill thick slices of portobello mushrooms or hearty cauliflower steaks with the chimichurri sauce for a satisfying plant-based meal.
• Spice it Up: Add smoked paprika or chipotle powder to the chimichurri for a smoky heat twist.
• Seasonal Veggies: Swap the summer vegetables with grilled asparagus in spring or sweet potatoes in fall for a seasonal touch.
• Low-Carb Version: Serve with cauliflower rice or a crisp green salad instead of the vegetables if you prefer a lighter plate.

One time, I tossed in some fresh mint into the chimichurri for a bright surprise that paired wonderfully with the grilled corn salad I served alongside, inspired by this refreshing grilled corn salad. It was an unexpected but delightful flavor combo that guests loved.

Serving & Storage Suggestions

This chimichurri flank steak with grilled vegetables is best served right off the grill, warm and vibrant. The steak slices are juicy and tender, while the vegetables still have that slight crispness and smokiness. I like to plate them simply, garnished with a little extra chimichurri drizzle and maybe a lemon wedge on the side.

For sides, this meal pairs well with crusty bread, a light salad, or even a creamy pasta dish like the creamy Tuscan chicken pasta if you want to round out the meal for guests.

Leftovers keep well in the fridge for up to 3 days in an airtight container. When reheating, gently warm the steak slices in a skillet or oven to avoid drying out, and refresh the veggies briefly on the grill or pan.

Flavors tend to deepen in the fridge as the chimichurri has more time to soak into the meat, so leftovers can be even tastier the next day. Just add a fresh spoonful of chimichurri when serving to brighten things back up.

Nutritional Information & Benefits

This recipe offers a balanced and nutrient-rich meal. A typical serving provides approximately 400-500 calories, with a solid protein boost from the flank steak (about 30-35 grams per serving), essential for muscle repair and satiety.

For those mindful of sodium, you can reduce added salt and rely on fresh herbs and acidity to keep flavors vibrant without overdoing it.

FAQs

What is the best way to slice flank steak for chimichurri?

Always slice flank steak thinly against the grain to ensure tenderness. This helps break down the muscle fibers and makes each bite easier to chew.

Can I make chimichurri sauce ahead of time?

Yes, chimichurri actually tastes better if made a few hours ahead or the day before, as it allows the flavors to meld. Store it in an airtight container in the fridge and bring to room temperature before serving.

How long should I marinate flank steak for chimichurri?

Marinate the steak for at least 30 minutes and up to 2 hours. Longer marinating can start to affect the texture because of the vinegar, so avoid exceeding 2 hours.

What if I don’t have a grill? Can I cook this indoors?

You can use a grill pan or cast iron skillet on the stove. While you won’t get the smoky flavor from an open grill, you can achieve great sear and caramelization indoors.

Can I freeze leftover chimichurri flank steak?

Yes, you can freeze cooked steak, but it’s best to freeze before slicing to preserve moisture. Thaw in the fridge overnight and reheat gently. The chimichurri sauce can be frozen separately or made fresh after thawing.
