This Easy Garlic Butter Flank Steak is a real treat! It’s juicy and bursting with flavor, thanks to the delicious garlic butter sauce that coats it perfectly.
Cooking it in the oven means no fussing with the grill, which is great for chilly evenings. I love serving it with mashed potatoes—such a comforting combo! 😋
Key Ingredients & Substitutions
Flank Steak: This cut is great because it’s flavorful and juicy. If you can’t find flank steak, skirt steak or sirloin can work well as substitutes. Just keep in mind that cook times may vary slightly with different cuts.
Unsalted Butter: I like using unsalted butter as it allows you to control the saltiness. If you’re out of butter, you could swap in ghee or a dairy-free alternative like coconut oil for a different flavor profile.
Garlic: Fresh garlic elevates the dish, but if you must use garlic powder, about 1 teaspoon will suffice. I recommend sticking with fresh when you can for that robust flavor.
Parsley: Fresh parsley adds a nice touch of color and freshness. Dried parsley works, but I suggest using double the amount since it’s less potent. For other options, thyme or rosemary can add a lovely twist too.
How Do I Get the Perfect Sear on My Steak?
Searing is crucial for flavor, so here’s how to do it right.
- Ensure the skillet is hot before adding the steak. This helps create a nice crust almost immediately.
- Don’t overcrowd the pan. If your skillet can’t hold the steak without crowding, sear in batches.
- Let the steak sear without moving it for those 2-3 minutes to develop a crust. Check for browning before flipping.
If you want a slightly charred flavor, you can finish the steak under the broiler for a minute or two after roasting! Just keep an eye on it to prevent burning.
How to Make Easy Garlic Butter Flank Steak in Oven

For the Steak:
- 1.5 to 2 pounds flank steak
- 1 tablespoon olive oil
- 1/2 teaspoon salt
- 1/2 teaspoon freshly ground black pepper

How Much Time Will You Need?
This recipe takes about 10 minutes of prep time and around 15 minutes to cook, with 5 minutes of resting time for the steak. In total, you can have a delicious meal ready in about 30 minutes!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by setting your oven to 425°F (220°C). This high temperature will help cook the steak evenly and give it a nice finish.
2. Prepare the Flank Steak:
Use paper towels to pat the flank steak dry. This helps it sear better. Season both sides with salt and pepper—don’t be shy; this will enhance the flavor!
3. Sear the Steak:
Heat the olive oil in an oven-safe skillet over medium-high heat. Once the oil is hot and shimmering, carefully add the flank steak. Let it sear for about 2-3 minutes on each side until you see a lovely brown crust forming. Be sure not to move it around too much during this time.
4. Prepare the Garlic Butter:
While the steak is searing, melt the butter in a small saucepan over low heat. Add in the minced garlic and parsley. Stir it for about a minute until it’s fragrant, but don’t let the garlic brown as it could become bitter.
5. Combine and Roast:
Once the steak has a nice sear, pour the garlic butter mixture over it in the skillet, making sure it’s well coated. Then, transfer the skillet to your preheated oven. Roast the steak for about 5-7 minutes for medium-rare, but you can adjust the time according to your preferred doneness.
6. Rest the Steak:
When it’s done, take the skillet out of the oven (be careful; it will be hot!) and move the steak to a cutting board. Let the steak rest for 5 minutes. This helps the juices redistribute, making it more tender!
7. Slice and Serve:
After resting, slice the steak thinly against the grain to ensure it stays tender. Serve the slices with the remaining garlic butter sauce drizzled over the top for extra flavor. Enjoy!
And there you have it—an easy, flavorful garlic butter flank steak straight from your oven!
