Blueberry Sauce For Your Meat is LEGIT
Y'all! I first tried steak with a blueberry balsamic reduction at Acqua Al 2 in DC many years ago. This authentically Italian restaurant is known for their filet mignon cooked in a blueberry reduction. I really liked the blueberry sauce because it was so unique (fruit on meat?! GASP!), so I knew I wanted to recreate this but with a more economical meat option that could be prepared on a weeknight.
Enter this easy, marinated flank steak with blueberry balsamic reduction. The only part you need to remember is to make the marinade in advance. The more time to marinate the better, but sometimes (hand up!) that's not always possible, so 30 minutes works in a pinch, too.

Preparing Your Flank Steak
Flank steak is a cut of beef that's typically very lean, so it can sometimes be on the tough side. This is why you usually see flank steak recipes that call for a marinade. It's an absolutely delicious piece of meat though. We eat flank steak about once a week -- it's our go-to weeknight steak option. The kids love it, we can double the recipe to last two nights, and it's just plain delicious.
You'll want to score your steak (just make cuts into the meat with your knife) so the marinade can seep into the flank steak as much as possible. This particular marinade uses just 4 ingredients (aside from S + P). The acidity of the balsamic vinegar tenderizes the steak and the olive oil keeps it juicy. Match made in heaven.
When your steak is cooked, make sure you cut the flank steak on the diagonal so you get wide pieces. This'll break up the muscle fibers to make double-sure you don't get a tough piece of meat in your mouth.
This Blueberry Sauce for All Meats
Don't limit yourself to flank steak either. Try using the blueberry sauce on chicken, pork chops, or if you want to get fancy -- give it a try with a nice filet.

Flank Steak with Blueberry Balsamic Sauce
Ingredients
- 1.5 pounds flank steak
For the marinade:
- 1 cup extra virgin olive oil
- ½ cup high quality balsamic vinegar
- 3 garlic cloves, minced
- 2 tablespoon rosemary, chopped
- ¼ teaspoon salt
- ¼ tsp pepper
For the blueberry balsamic sauce:
- 2 tablespoon high quality balsamic vinegar
- 1 cup fresh blueberries
- 1 teaspoon brown sugar*
- 1 tablespoon freshly squeezed lemon juice
Instructions
- Lay out flank steak on cutting board or parchment paper. Score the steak with a knife to allow marinade to seep into the steak. Set aside.
- Put marinade ingredients in a small bowl. Stir until well combined. Transfer meat and marinade to a double-lined freezer bag. Be sure all parts of the meat get covered in the marinade by squishing it all around. Let it rest for at least 30 minutes or overnight if possible.
- Turn on your oven's broiler.
- On a roasting rack, cook the meat under the broiler for 6 minutes per side for medium-rare cooked steak. Take steak out of the oven once both sides have cooked and let rest for 10 minutes.
- While steak is resting, combine all ingredients in a small sauce pan. Over medium heat, boil blueberry mixture until blueberries break down and mixture is reduced (about 6-8 minutes).
- Pour blueberry balsamic mixture over cut steak and enjoy!

Have eaten the Filletto al Mirtillo at Acqua al Due in Firenze several times. Might be my favorite meal ever. In my whole life. Thanks, gonna try to recreate it with your inspiration!
Kathryn says
What a dream! I bet that was an amazing meal!
Christine says
I just picked a ton of haskap berries so I used them in the sauce. This is really delicious! The Rosemary with the berries is killer! I went one step further and placed a thick slice of Cambozola cheese on the steak when it was done cooking. The oozy goodness of the cheese with everything else is something very special!
Kathryn says
That sounds heavenly, Christine!
