BLENDITARIAN CHALLENGE SERIES
Prelude: Blenditarian.Com has initiated a monthly challenge that incorporates their Blenditarian approach into interesting and fun dishes. To clarify for my readers, a Blenditarian is “one who believes the mighty, meaty mushroom makes meals more delicious, nutritious and sustainable.” This approach stretches ground meat by adding finely chopped mushrooms to create a flavourful and more nutritious dish. The theme for the May is “National Burger Month” Blenditarian Challenge.” The challenge is to create a blended burger by incorporating The Blend (mushrooms + ground meat).” For this reason, I have developed a recipe called The Ultimate Blended Burger.
This burger is unique in that it not only incorporates minced mushrooms into a beef/pork mixture; it also contains rehydrated dried vegetable flakes, contributing even more flavour to the burger. Barbeque season is just around the corner – give these burgers a try. They are delicious!
The Ultimate Blended Burger
Burger Chef Tips:
- In this recipe, the meat is seasoned during the mixing of the burger meat. This simple step enhances the flavour experience of every bite.
- The recipe utilizes a ratio between beef, pork and mushrooms:
- Pork adds more flavour to the burger
- Pork will add moisture and fat to the burger as lean or extra lean beef can often result in a dry burger. NOTE: The ratio of beef to pork can be changed to suit personal preferences.
- Mushrooms add a rich earthy flavour, in addition to stretching the meat when creating the ‘blend’. I prefer using Cremini mushrooms for their ‘meaty’ flavour and dark appearance when cooked.
- Bear in mind that with the addition of pork, the burger will shrink more than an all-beef burger. Therefore, purchase your buns with that in mind. When making the burger patties, adjust the size to allow for shrinkage.
- If you can find sourdough hamburger buns, their flavour will make a tasty difference. Buttering and toasting the cut edges of the sourdough bun is a must! The crunchy interior of the bun adds an element of texture to the overall burger.
- The experienced griller will understand that the additional fat from the pork will cause lots of flames, so I would recommend barbecuing these burgers over indirect heat.
- With the additional fat content in the burgers, they will typically cook a bit faster than normal all-beef burgers, so keep a close watch on them. For those who utilize thermometers to determine doneness, the Canadian Food Inspection Agency and USDA recommend a temperature of 160oF or 71oC to ensure your burgers are cooked safely.
The Ultimate Blended Burger
INGREDIENTS:
MUSHROOM/VEGETABLE MIXTURE
- 1 Tablespoon olive oil
- 8 oz. (226 g) Cremini mushroom (about 7 large Cremini)
- 1 – 2 cloves of fresh garlic, finely minced
- ½ teaspoon onion salt
- ½ teaspoon ground black pepper
- 2 Tablespoons dried vegetable flakes, rehydrated in ½ cup hot water, optional
MEAT MIXTURE
- 1 lb. (454 g) lean ground beef
- 1 lb. (454 g) ground pork
- 1 cup fresh breadcrumbs (gluten-free bread crumbs if required)
- 1 egg, large
- 1 teaspoon fine sea salt
- 1 teaspoon ground black pepper
- 1 Tablespoon Worcestershire sauce
- 1 teaspoon onion salt
- ¼ cup finely sliced green onion
METHOD:
- Place the olive oil in a small frying pan. Add the minced mushrooms and minced garlic. Cook over medium-low heat until the mushrooms are cooked and any moisture is evaporated. Cool completely.
- Place the vegetable flakes into a glass measuring cup. Pour hot water over it and let it sit for 5 minutes. Drain any excess water. Mince the softened vegetables finely.
- In a large bowl, place the cooled mushroom/garlic mixture and the minced vegetable flakes. Add the meat mixture ingredients and stir until well mixed. (Do not over handle the mixture). CHEF TIP: Take a tablespoon size amount of the mixture and make a small patty. Cook this small sample in a frying pan and taste for seasoning. Adjust the mixture to taste using the ingredients from above. Once the mixture is at the preferred level of flavour, portion and shape the mixture into patties, barbeque and enjoy!
ADDITIONAL NOTES:
- To achieve maximum flavour, refrigerate the patties for several hours so the flavours marry nicely.
- These burgers freeze well. CHEF TIP: place a small square of parchment or wax paper in between each patty when freezing. This makes separating the frozen patties easier.
TOPPING OPTIONS: (Use your favourite toppings or the following suggestions)
My favourite hamburger toppings for the Ultimate Blended Burger are as follows:
- Cheddar Cheese (Old), sliced
- Fresh tomatoes, sliced
- Lettuce leaves
- White Onions, sliced
- Dill Pickles
- Garlic Aioli (another personal favourite) or mayonnaise
Here is your visual step-by-step:

The ingredients for the Ultimate Blended Burger include pork, beef, mushrooms, dried vegetable flakes, garlic, breadcrumbs, egg, green onion and seasonings

If you look closely you can detect the specks of sauteed mushrooms and rehydrated vegetable flakes in the burgers, both of which add flavour to the burgers

The mixture makes 12 1/4 lb. burgers. Use them immediately or freeze them.

I’m salivating over this delicious looking burger, Denise! Looks and, I’m sure, tastes, amazing!
Thanks, Colleen! It is a delicious and moist burger.
Great photos Denise! So this sounds interesting and I bet it tastes great. I like using pork – although it’s not part of my culture to eat meat every single day. I bet some people think only of beef when they think of burgers. Overall I have no doubt the mixture would work. Am a bit stumped by the veggie flakes – will look for those! Going to sign up for your newsletters – always good stuff from your kitchen!
Thanks so much for your kind words, comments and for signing up for my newsletters, Diane! We started using the dehydrated vegetable flakes when my daughter had to follow a grain-free diet for awhile. My husband was the one who thought of using the rehydrated vegetable flakes as puree instead of bread crumbs and we have been doing it this way ever since because the vegetables add so much flavour to ground meat mixtures (meatloaves, meatballs, hamburgers). They are available at bulk food stores or in the bulk food section of your grocery store. If you try it, let me know what you think!
You included such great tips for the burger grill season! Ultimate burger for sure.
I generally go with an all beef burger but will have to try it with the inclusion of pork as well.
I am excited to hear if you try the inclusion of pork into your next hamburger making session, Melissa. I think you will like it. Thanks for your great comments.
What a great way to add flavour and up the veggie quotient! I had never heard of ‘Blendetarian’ before but it makes good sense! Thanks for sharing!
Thank you, Carolyn! I hope you get a chance to try these moist burgers. They are delicious! The mushrooms and vegetable flakes add so much flavour!
What a grand idea. We have ground 50/50 beef/pork blend (Blandfärs) available in our market, so I’m half way there. We usually have grilled burgers once or twice a month in the warm months, so this will go right to our must make list.
Thanks so much, Ron. I think you will enjoy this Blenditarian burger – it is substantial and a more sustainable approach using the mushrooms. I look forward to hearing what you think of it when you try it. Thanks for stopping by!
