Meet your new favorite balsamic vinegar steak marinade! This 5-ingredient sirloin steak marinade is bound to become a favorite because it’s SO easy and uses common pantry ingredients that you probably already have. It’s truly the BEST easy balsamic steak marinade recipe out there.
This amazing, easy steak marinade works well for just about any cut of meat, but I especially love it on sirloin steaks. My post for how to cook sirloin steak in the oven (coming soon!) will show you my easy cooking process – no grill required.
As much as I love grilling and spending time outdoors, I must say that my favorite way to cook steaks is a quick sear on a really hot pan, and then finishing it in the oven until it reaches the level of doneness you want. (I’m a medium or sometimes medium-rare kind of girl, but you do you!)
How To Make Steak Marinade With Balsamic
This quick steak marinade takes less than 5 minutes to make and all it takes is 5 easy ingredients!
First, you’ll want to whisk all of the ingredients together in a bowl.
Then, pour the marinade into a plastic bag, add the steaks, and move them around a bit so that all of the steaks are covered in some of the marinade.
Refrigerate the meat for 3 to 8 hours!
TIP: The optimal marinating time is between 3 and 8 hours, but not longer. The meat can get mushy if it sits too long in the marinade.
Remove the steaks from the refrigerator about 30 minutes before you want to cook them to let them come to room temperature a bit. This will help them cook evenly.
TIP: Store the bag in a glass bowl or container and if you’re around, flip and rotate the bags of steak every so often. This isn’t required, but will help ensure that the top sirloin steak marinade is coating all of the meat well.
After marinating the steaks, cook them using your favorite method – typically either on the grill or in the oven. Here is how to cook steak in the oven.
Is Balsamic Vinegar A Good Marinade For Steak?
Yes. Balsamic vinegar is a good marinade for steaks for two reasons. It helps:
- Tenderize: The acid in this great steak marinade help to break down some of the protein and fat in the beef, which makes it more tender.
- Flavor: The balsamic vinegar also adds a subtle sweet flavor, without adding any sugars or sweeteners. While the dark vinegar stands up to flavorful red meat, you could also swap it for white wine vinegar and try this marinade on chicken or fish.
Can You Make Balsamic Vinegar Steak Marinade Ahead?
Yes, you can make balsamic vinegar steak marinade ahead.
The only thing you want to be careful of is actual marinating time. Three to eight hours is recommended as it is enough time to tenderize the meat and give it flavor, but not too long as to make the meat mushy.
So you can make the marinade ahead, but don’t add the meat to it until the day you are cooking the meat.
The marinade will last 4-5 days. Store in an airtight container in the refrigerator. If the oil solidifies, simply take it out and let it come to room temperature before using or run the container under warm water.
Should You Marinate Steak In The Fridge?
Yes, you should marinate steak in the fridge if you will be marinating it longer than 30 minutes. While we want to remove the steak from the refrigerator prior to cooking, we don’t want it sitting out at room temperature for extended periods of time.

Are these nutrient facts for just the marinade or the marinade plus steak?
Maya | Wholesome Yum
Hi Breanna, The nutrition info includes the steak. I thought that was more useful than just the marinade by itself.
Emily
Love this marinade. I’ve been missing the taste of balsamic vinegar since I’ve been doing low carb. So happy to find a recipe with the same taste but none of the carbs.
Chrissy
Love this easy recipe! I usually do some sauteed mushrooms with my steak, but wanted something a little different. Had coconut aminos that I hadn’t got around to using yet so tried this. Super good. Love the balsamic flavor combo with the meat.
