Ingredients for Chimichurri Marinated Flank Steak

Grab these simple ingredients – most might already be in your kitchen! The magic happens when fresh herbs meet good-quality steak:

• 1 lb flank steak (look for even thickness)
• 1/2 teaspoon chili powder (smoked adds bonus depth)
• 1/2 teaspoon each salt & pepper (I use coarse sea salt)
• 1 lemon or lime, halved (for that bright finish)
• 1/2 cup chimichurri sauce (recipe below – you’ll want extra!)

Chimichurri Sauce Ingredients

This vibrant green sauce is the star – use the freshest herbs you can find:

• 1 bunch parsley (about 1 1/2-2 cups packed leaves)
• 1 cup olive oil (good quality makes a difference)
• 5 cloves garlic, smashed (more if you’re brave!)
• 1/4 cup red wine vinegar (or sub lemon juice in a pinch)
• 1/2-1 teaspoon crushed red pepper flakes (adjust to your heat tolerance)
• 1 tablespoon dried oregano (rub between palms to wake it up)
• 1/4 teaspoon each salt & pepper (taste and adjust later)

How to Make Chimichurri Marinated Flank Steak

Okay, let’s get cooking! First things first – heat your grill or grill pan to medium-high. You want those flames ready to give your steak that perfect char. While it heats, pat your flank steak dry (this helps with browning!) and rub it all over with the chili powder, salt, and pepper. No need to marinate for hours – this cut cooks fast!

Now, grill time! Place that beautiful steak on the hot grates and don’t touch it for 6-8 minutes. Resist the urge to poke! Flip it once using tongs (forks steal juices) and cook another 6-8 minutes for medium-well. Here’s my secret: if the steak feels like the fleshy part of your palm below the thumb when pressed, it’s done. Remove it to a cutting board and let it rest for 5 crucial minutes – this keeps all those juices inside where they belong.

While it rests, squeeze fresh lemon or lime over the top (that acidity cuts through the richness perfectly). Finally, slice against the grain in thin strips – this makes even tough cuts tender. Pile it high on a platter and drown it in that vibrant chimichurri sauce. Oh, and don’t be shy with extra sauce on the side for dipping!

Preparing the Chimichurri Sauce

While the grill heats, make your sauce. Finely chop the parsley and garlic – I like mine with some texture, not puréed. Dump everything into a bowl and whisk like you mean it! The oil and vinegar will emulsify into this magical green elixir. Taste and adjust – more salt? More heat? It’s your sauce now. Pro tip: Make it an hour ahead if you can – the flavors marry beautifully as it sits. Leftovers keep for weeks in the fridge (if they last that long).

Tips for Perfect Chimichurri Marinated Flank Steak

After making this recipe dozens of times (and learning from my mistakes!), here are my can’t-skip tips:

• Steak temp matters: Take the meat out of the fridge 30 minutes before grilling – room temp cooks more evenly
• Slice smart: Always cut against the grain (those little muscle fibers) for tender bites
• Sauce storage: Keep chimichurri in a mason jar with olive oil on top – lasts weeks!
• Don’t crowd: Give steak space on the grill for proper caramelization
• Resting rule: Those 5 minutes post-grilling make ALL the difference in juiciness

Oh, and one bonus tip? Make double the chimichurri – you’ll want it on eggs, sandwiches, even spooned over roasted potatoes tomorrow!

Serving Suggestions for Chimichurri Marinated Flank Steak

Oh, the possibilities! This steak shines alongside simple grilled veggies – zucchini and bell peppers love chimichurri too. For heartier meals, pair with garlic rice or buttery roasted potatoes. My go-to? A bright tomato and avocado salad to balance the richness. Always, always serve extra chimichurri on the side – for drizzling, dipping, or just eating by the spoonful (I won’t judge!). Leftovers? Toss thin slices into tacos or over greens for next-day magic.

Storing and Reheating Chimichurri Marinated Flank Steak

Here’s the good news – leftovers taste even better! Store sliced steak in an airtight container for up to 3 days in the fridge. The chimichurri sauce? It gets happier with time and keeps for 2 weeks refrigerated (or freeze portions for a month). When reheating, go gentle – microwave steak slices in 15-second bursts or warm briefly in a skillet with a splash of broth to keep it tender. Honestly though? I usually eat it cold straight from the fridge – the flavors intensify overnight!

Chimichurri Marinated Flank Steak FAQs

I get asked these questions all the time – here’s everything you need to know:

Can I use skirt steak instead? Absolutely! Skirt steak works beautifully – just reduce cooking time by 1-2 minutes per side since it’s thinner. The chimichurri clings to those grooves perfectly.

How long should I marinate? Honestly? Zero minutes needed! Flank steak absorbs flavors fast. If you must marinate, 30 minutes max – any longer and the acid starts “cooking” the meat.

Is chimichurri spicy? Only if you want it to be! Start with 1/2 teaspoon red pepper flakes, then add more to taste. The parsley and oil balance the heat beautifully.

Can I make this indoors? Of course! A screaming hot cast iron skillet gives gorgeous crust. Just open your windows – it’ll get smoky (but oh-so-worth-it).

Why rest the steak? Those precious minutes let juices redistribute. Skip this step and they’ll end up on your cutting board instead of in your mouth!

Nutritional Information

Just a heads up – these numbers are estimates since ingredients vary. Per serving (about 4 oz steak + sauce), you’re looking at roughly 450 calories, 35g fat (mostly the good olive oil kind!), and 30g protein. Not bad for something this delicious, right? The chimichurri packs vitamin C from all those fresh herbs too – consider it your tasty multivitamin!
