These umami-packed Big-O Bacon Burgers will be a hit with the whole family because who doesn’t a juicy burger made with bacon, mushrooms, and beef!

The most umami-packed burgers!

Warning: this recipe is dangerous. Not only is it one heck of a crowd-pleaser, but your family and friends will be kicking down your front door for a seat at your dinner table. Heed my words.

Featured in our first cookbook, Nom Nom Paleo: Food for Humans, this is a burger recipe that heaps umami on top of umami. These days, more and more restaurants and food pros are grinding bacon with beef to form their special burger blends, but like many of you, I don’t have a meat grinder on hand in my kitchen.

My solution? Freeze the bacon, roughly chop it, and then pulse it in your food processor before mixing it with ground beef. (Remember to use sugar-free bacon to keep it Whole30-friendly!) Plus, I add cooked-and-cooled minced mushrooms for an extra blast of flavor power.

I usually eat these burgers in a lettuce wrap…

…but if you have time, I highly recommend roasting Portobello mushroom caps and using them as “buns.” And don’t forget to load up the toppings!

Ingredients

  • Cremini mushrooms: No need for fancy mushrooms here! Just use brown or white button mushrooms.
  • Bacon: I wrap my bacon in 4 ounce portions and keep it in the freezer just for this recipe! If you don’t freeze it, you’ll make a gooey mess when you chop it in the food processor.
  • Ground beef: It’s fine to use the super lean ground beef because you’ll be mixing it with bacon! You can also use ground turkey, but I think ground beef or bison taste the best.
  • Diamond Crystal kosher salt: No need for fancy seasoning, but I have used my Magic Mushroom Powder in place of salt in this recipe and it is SPECTACULAR.
  • Freshly ground black pepper
  • Ghee, lard, or fat of choice: for frying the burgers

How to make Big-O Bacon Burgers!

Heat your favorite high temperature cooking fat in a cast-iron skillet over medium heat, and sauté the mushrooms until the liquid they released has cooked off. Set aside the cooked mushrooms to cool to room temperature.

Fry up the patties in the hot fat, turning once. They should take about 3 minutes per side, whereas sliders should only take about 2 minutes per side. Of course, you are free to cook ’em as well-done as you wish.

    These were so easy and flavorful! We had a pack of meat a little over a pound, so our burgers were a bit bigger. When you bite into them they have just right amount of salt and juiciness. I even think people who don’t like mushrooms would appreciate these burgers.

  2. I bought Michelle’s book, Nom Nom Paleo food for humans this week and this is my first recipe from it I used. I just made this recipe for my family tonight, and drool. What an awesome recipe. I was nervous, this recipe includes a ton of mushrooms, and I am the only one in the house that likes mushrooms. Before I could get the burgers cooking, my husband came home from work and was commenting on how the house smelled like mushrooms. But, everyone ate them and, they agree it’s a winning recipe. Thanks for such a great recipe.

    I really enjoyed this recipe. I think the mushrooms in the burger really added another layer of flavor without it being necessarily a discernible mushroom flavor. I ended up using some double smoked bacon which I had in the fridge and it gave the burgers a real yummy smoky bacon flavor. I didn’t think about this until after I had mixed the raw bacon into the hamburger meat, However, I like my burgers pink on the inside, but with raw bacon in the patties, I felt that I had to cook them until there was no more pink to make sure that the bacon was fully cooked. When I cook this recipe again, I think I will cook my bacon and reduce it to a fine crumble before adding it to the burger meat so that I can leave my burger patties medium rare without worrying about eating uncooked bacon.

    Outstanding! The mushrooms and bacon took these burgers to a new level! We’ll be making these again soon!
