What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients to deliver bold flavor with minimal fuss. Most are pantry staples or easy to find at any grocery store, and you can swap a few depending on your pantry or dietary needs.

• Flank steak (about 1.5 pounds / 680 grams): Look for a well-marbled piece for best flavor and tenderness.
• Bell peppers (3 medium, assorted colors): Red, yellow, and orange peppers bring sweetness and vibrant color.
• Olive oil (3 tablespoons): Use a good quality extra virgin olive oil for dressing and roasting.
• Garlic (4 cloves, minced): Adds that punchy aroma and depth.
• Fresh parsley (1 cup, packed, finely chopped): The star herb for the chimichurri’s fresh flavor.
• Fresh cilantro (½ cup, chopped): Adds bright, citrusy notes to the sauce.
• Red wine vinegar (2 tablespoons): Balances the richness with acidity.
• Red pepper flakes (¼ teaspoon, optional): For a gentle kick of heat.
• Salt and freshly ground black pepper: To taste, seasoning both the steak and vegetables.
• Lemon juice (1 tablespoon): Freshly squeezed, to brighten the chimichurri.
• Optional extras: A splash of smoked paprika or cumin in the seasoning mix can add a smoky twist; swap parsley or cilantro with fresh oregano or basil for a different herb profile.

For substitutions, if you want a dairy-free or vegan chimichurri twist, consider blending in avocado for creaminess. Also, if you prefer a milder herb sauce, reduce the cilantro and add more parsley. I usually recommend Cortland Olive Oil for its smooth flavor, but any good brand will do.

Equipment Needed

• Large rimmed sheet pan: A sturdy, heavy-duty pan works best to hold all the ingredients and handle high heat. I’ve found that pans with a non-stick coating or stainless steel perform well here.
• Mixing bowls: For tossing peppers and mixing chimichurri.
• Sharp knife and cutting board: Essential for slicing the flank steak thinly against the grain.
• Food processor or blender (optional): For a quicker chimichurri blend, though chopping by hand works just fine and adds a rustic texture.
• Tongs: Helpful for flipping the steak and tossing the vegetables.

If you don’t have a food processor, a well-sharpened chef’s knife will do just fine chopping the herbs and garlic. For budget-friendly options, a basic rimmed baking sheet and sturdy mixing bowls can be found inexpensively at most stores. Just avoid overcrowding the pan to keep that perfect roast.

Preparation Method

1. Preheat your oven: Set it to 425°F (220°C). This high heat is key for roasting the peppers and searing the steak on the sheet pan.
2. Prepare the flank steak: Pat the steak dry with paper towels to encourage good browning. Season generously with salt, pepper, and a drizzle of olive oil. Let it sit at room temperature for about 10 minutes while prepping the veggies.
3. Slice and toss the peppers: Core and seed the bell peppers, then cut into strips about ½ inch thick. Toss them in a bowl with 1 tablespoon olive oil, a pinch of salt, and some freshly cracked black pepper.
4. Arrange on the sheet pan: Spread the peppers in an even layer on one side of the sheet pan. Place the flank steak on the other side. This lets the steak roast without steaming and the peppers caramelize beautifully.
5. Roast for 15-20 minutes: Roast the steak and peppers together, flipping the steak halfway through (about 10 minutes in). The steak should reach an internal temperature of 130°F (54°C) for medium-rare. Use a meat thermometer if you have one.
6. Make the chimichurri sauce: While the steak roasts, combine minced garlic, chopped parsley, cilantro, red wine vinegar, lemon juice, red pepper flakes, salt, pepper, and 2 tablespoons olive oil in a bowl or food processor. Pulse until well combined but still a bit chunky for texture.
7. Rest the steak: Once cooked, transfer the steak to a cutting board and tent loosely with foil. Let it rest at least 5 minutes to lock in the juices.
8. Slice the steak: Cut thinly against the grain into bite-sized strips. This keeps the meat tender and easy to eat.
9. Serve: Arrange sliced steak alongside the roasted peppers on a platter and drizzle generously with chimichurri sauce.

Pro tip: If your peppers start browning too fast, you can loosely cover the pan with foil for the last 5 minutes to prevent burning. Also, letting the steak rest is crucial—it’s something I learned the hard way after a dry dinner once!

Cooking Tips & Techniques

Getting the perfect flank steak texture and flavor can be a bit of a balancing act, but here are some tips that have saved me from mistakes and made this recipe a winner every time.

• Don’t skip patting the steak dry: Moisture is the enemy of a good crust. I always blot the steak with paper towels before seasoning.
• Room temperature steak roasts more evenly: Letting it sit out for 10-15 minutes helps avoid tough edges and uneven cooking.
• Use a meat thermometer: Flank steak cooks quickly, and it’s easy to overshoot. Aim for 130°F (54°C) for medium-rare, and carryover heat will finish it off during resting.
• Chimichurri texture matters: I prefer a slightly chunky chimichurri over a smooth sauce because it adds a nice bite and fresh herb bursts with every forkful.
• Roasting peppers on the same pan saves time: But don’t overcrowd! Give the peppers room so they caramelize instead of steaming.
• Slice against the grain: This is key to tender steak every time. I learned this after serving tough bites to friends once—never again!

Also, multitasking is your friend here—start chimichurri while the steak roasts, and you’ll have everything ready in perfect sync. If you’re curious about other sheet pan dinners, you might enjoy my spicy Cajun shrimp and sausage sheet pan meal for a different flavor vibe but equally simple prep.

Variations & Adaptations

This recipe is flexible, and I’ve played around with several variations depending on the season and what’s in my fridge.

• Dietary swaps: For a gluten-free option, this recipe is naturally safe—just double-check your vinegar and spices. You can swap flank steak for skirt steak or even a boneless sirloin if you prefer.
• Seasonal twists: In late summer, I swap out bell peppers for charred cherry tomatoes or zucchini slices for a lighter feel.
• Flavor upgrades: Add a sprinkle of smoked paprika or cumin to the steak seasoning for a smoky depth. Or try swapping out cilantro in the chimichurri for fresh oregano or basil for a different herb profile.
• Cooking method changes: If you want to grill instead of roast, you can cook the steak on direct heat for about 4-5 minutes per side and roast peppers separately in a hot oven or grill basket.
• Personal favorite variation: One time, I added crumbled feta and toasted pine nuts on top just before serving—an unexpected little Mediterranean twist that was a crowd pleaser.

Serving & Storage Suggestions

I like serving this savory sheet pan flank steak with chimichurri and roasted peppers warm, right after slicing and drizzling. It pairs beautifully with simple sides like a crisp green salad, roasted potatoes, or even a warm grain like quinoa or rice.

For a full meal, try pairing with the easy one-pan garlic butter salmon with asparagus for a pescatarian option on a different night or with roasted vegetables for a hearty plate.

To store leftovers, keep steak and peppers in airtight containers in the fridge for up to 3 days. Reheat gently in a skillet over medium heat or in the oven at 300°F (150°C) to avoid drying out. The chimichurri is best kept separate and added fresh each time.

Flavors actually deepen after a day or two, making it a great meal prep option to enjoy throughout the week.

Frequently Asked Questions

Can I use a different cut of steak instead of flank steak?

Yes! Skirt steak or sirloin can work well, but flank steak is preferred for its texture and ability to absorb marinades. Just adjust cooking times accordingly.

How do I make the chimichurri sauce ahead of time?

Chimichurri can be made up to 24 hours in advance and stored in the fridge. Bring it back to room temperature before serving for best flavor.

What if I don’t have a meat thermometer?

Use the touch test: the steak should feel slightly springy for medium-rare. Alternatively, cook 4-5 minutes per side and rest before slicing thinly.

Can I grill the steak and peppers instead of roasting?

Absolutely. Grill the steak over medium-high heat for 4-5 minutes per side and roast or grill peppers separately in a grill basket or foil packet.

Is this recipe suitable for meal prep?

Definitely. Store steak and peppers separately from chimichurri in airtight containers and reheat gently. The flavors even improve after a day!
