This mushroom burger is juicy and flavorful. I’ve hidden the mushrooms texture by chopping them very fine. Then we saute them and the onion to caramelize their flavor. It turns into a wow burger bursting with flavor. Give it a try and let me know what you think in the comments below.

Mushroom burger recipe

1 lb. grass fed beef, more fat content is better when making burgers
12 – 14 medium size cremini mushrooms, cleaned, trimmed and cut in half
1 yellow onion, finely diced
2 Tbsp. Bbq sauce
2 tsp. Sriracha sauce or to taste
Garlic powder
Cheese, american, cheddar or your favorite

Homegrown tomatoes
Sliced avocado


Start by wiping the mushrooms with a paper towel to remove any dirt. Cut off part of the stem and then slice the mushroom in half. Place all the mushrooms in a food processor and pulse until the texture is very finely chopped.

Preheat a large fry pan over medium high heat. Add 1 to 2 tablespoons of olive oil and let it heat up for 30 seconds and add the onion and mushrooms. Saute for 15 minutes turning the heat down to medium low after 3 or 4 minutes. Stir frequently.

Let the onion/mushroom mixture cool before continuing on.

In a large bowl, add the following: the cooled onion mixture, sriracha sauce, bbq sauce, garlic powder and salt. Mix this until well combined.

Next add the hamburger by dropping in 1 inch size chunks. This will make it easier to mix the ingredients together without over mixing the beef.

Form 4 hamburger patties and press a dent in the center of each burger about 1 inch in diameter. This will help your burger cook up with a flat top making it easier for those condiments to stay on top.

Preheat a grill pan or frying pan to medium high heat. Place the patties on the grill and season with a little more salt and garlic powder. Cook about 3 minutes per side before flipping over. I like to place a lid as per the video to help cook the burger.

Use an instant read thermometer to check the internal temperature of your burger. A 160 degree F. reading is done. I like to take them off the grill at just under 160 degrees F because it will continue to cook as the burger cools for a couple minutes.

If you are adding cheese to your burger, you will want to do so during the last minute or two of cooking.

I also like to toast up my bread or buns. I like to place a bit of butter to each half of the the buns which adds a nice flavor to your burger.

Ready to put it all together? Place that juicy burger on a toasted bun, then add the pattie and top it with some sliced tomato, avocado and whatever else pleases you!
