Delicious patties! I let the mixture rest in the fridge for a few hours before panfrying the patties and they had a really nice texture. They didn't fall appart like most bean burgers 😄

My meat-eating family thought these were great but a bit too spicy altogether. Next time we’ll put much less adobo & spice. But it’s a keeper.

We used kidney beans instead of pinto beans and used different but similar sauces. The burgers were delicious and if you're careful, they are stable enough. I can recommend adding vegan cheese on top once you've flipped them and closing the pan with a lid, so the cheese can melt.

So happy to hear you enjoyed the burgers, Julia! A lovely idea to use kidney beans as well :)

So many great PUL recipes, but this was a miss for me, and way too much onion in the burgers - ‘medium’ isn’t measurement.
(Also, what’s 1/2 tbsp? It’s like saying 1/7 cup. Might look neater in recipe, but it’s not an actual measurement either.)

PUL small logo PUL Team - Feb. 22, 2024, 6:05 p.m.

Hey Rút, we're sorry to hear this recipe was a miss for you, but appreciate the feedback! One medium onion for us is around 110 grams (3.9 ounces). Half a tablespoon (tbsp) is equal to one and a half teaspoons.

Rút - Feb. 23, 2024, 12:31 p.m.

Ah, onion grammes/ounces would have been really useful to know! Why not just put 1 1/2 tsps in recipe?

PUL small logo PUL Team - Feb. 23, 2024, 8:22 p.m.

Hey Rút, the half-tablespoon measurement is commonly used and is labeled as 1/2 Tbsp here in the Netherlands, and in a similar way in Canada. It is possible, though, that some manufacturers of measuring spoons might not include this specific size in their sets. We've decided to maintain the use of 1/2 Tbsp because it allows for measuring with a single utensil, which makes the process faster, as opposed to using two utensils (a 1 tsp measuring spoon and a 1/2 tsp measuring spoon). I hope this helps :)

Rút - Feb. 24, 2024, 10:49 p.m.

Ah, we’ve different 3 sets of measuring spoons and none have that measure; we won’t be buying another set! Maybe a key somewhere would be useful? 1/2 tbsp = 3 x 1/2 tsp; medium onion = 110g etc

Also noticed the app changes ‘my recipe’ measurements to 1/2tbsp when it’s specifically not entered. That’s a bit frustrating, especially for own recipes.

loved it! I made it with lentils and wasn't able to mash them as thoroughly as I wanted to. maybe if I first mashed them in a bowl on their own, or even put them in a food processor, they would have come out better. as it is the patties are a little unstable. I still love this recipe though!

The burgers were delicious and pretty fast and easy to make. 😄👍 We added some glazed onions and guacamole and iceberg lettuce instead of rocket and coleslaw because that's what we had and our was still really good!

These were so tasty! I added extra glazed onions to the red paprika’s and mushrooms and I doubled the chipotle sauce.

Can i make these in the bbq?

PUL small logo PUL Team - Aug. 18, 2023, 8 a.m.

Hey Katerina, we haven't tested out barbecuing these patties, but we don't imagine they would grill well as the patties are rather soft. Frying on the pan is the best bet for these ones to ensure they hold their shape 🤗

Just used this recipe for the patties. They were really easy to make! Especially with a food processor :) didn’t see salt listed in the ingredients but I did seasoned them with a little salt. Perfect recipe for some healthy and wholesome comfort food☺️

PUL small logo PUL Team - Aug. 5, 2023, 9:25 p.m.

Hey Jella, so glad you enjoyed this recipe! Our cajun seasoning is rather salty, which is why we chose to omit salt from our ingredient list, but of course, you can add more to your preference 😊

Jella - Aug. 7, 2023, 8:40 p.m.

Didn’t realize Cajun seasoning had salt in it. Also didn’t have any at home😆 so I spiced it up with some chili powder instead 😁

Diana - July 23, 2023, 1:29 a.m.

Really good burgers, but there was too much onion in my mix. I'd greatly appreciate weights and measures for the onion in your recipes since "medium" is not terribly objective. Easy edit for next time. Thanks, as always.

Hey Diana, thanks for sharing the feedback! In the meantime, in case it helps, our medium onions are around 110 grams 😊

I only made the patties. The recipe Is very good with lots of healthy ingreditents. I always make them ahead and freeze them so I can later have them ready to go when I want some burgers.

Thank you for this recipe, i'm planning to do it for 25 persons tomorrow, and I was wondering if I could cook these patties in the oven... what do you think?

PUL small logo PUL Team - Feb. 23, 2023, 7:02 p.m.

Hey Elsa, mmm so many burgers! We haven't tested this recipe in the oven but imagine you could. For example, perhaps 375°F for 10 minutes per side is a starting point. We'd suggest keeping a closer eye on the patties though since every oven tends to be different. If the burger patties don't get as crispy as desired, you could also broil them shortly 😊

My favourite burgers to make for my family. I add the sauteed mushrooms ( pepper) to my burger mix, so delicious! I usually batch make these and keep them in the freezer!

Delicious and fairly easy to make! The burger patties had a really sticky consistency, but they formed just fine and easily flipped. Next time, I’ll cook a bit lower and slower, so the inside gets more cooked. Didn’t make the Cajun Mayo, but made the mushroom/red bell topping. Love this burger!

PUL small logo PUL Team - July 27, 2021, 7:43 p.m.

So glad you enjoyed the burgers, Luci! To help with the sticky consistency when forming the patties, using a touch of flour or wet hands may help a bit ☺️

Is there a substitute for pinto beans? Can I use kidney or cannellini beans instead? Will the quantity remain the same?

PUL small logo PUL Team - June 13, 2021, 12:10 a.m.

Hello Zee, lovely question! You can substitute the pinto beans for another cooked bean of your choice, such as kidney beans, or cooked brown lentils. The quantity will remain the same 🙂

Hagit - June 8, 2021, 7:25 p.m.

Hi, looks so good! is there an optional substitute for the flaxseeds?

PUL small logo PUL Team - June 9, 2021, 6:17 a.m.

Hey there, Hagit, that's a great question! The ground flax seeds in water form a gel that helps act as a glue so the burger patties bind together. You could substitute the ground flax seeds for another ground seed, such as chia seeds, as ground chia seeds work well as a substitute!

Alternatively, you could experiment with some other ingredients that act as a binder, such as mashed banana, apple sauce, or a commercial egg replacer. These may impact the patty as they're generally sweeter in taste though. Let us know how it goes if you give any of these ideas a try 😃

Chris - May 18, 2021, 12:55 p.m.

Amazing recipe! 😋

If I'm not mistaken, the amount of cooked pinto beans should be somewhere around 240 g.

So glad you enjoyed the recipe, Chris, and great catch! Thank you for pointing that out and bearing with any confusion the initial number had. It's been updated ✨☺️
