French Green Lentil Burger feat. Revival Provisions Mustard!!

I went into my pantry this week to see what kind of burger I could whip up without going to the store (more or less), and I found these beautiful French green lentils!

These lentils are dotted with black spots when raw. When cooked, the black part seems to dissolve into the broth, resulting in a deep, beautiful color in the pot.

I was told these lentils are a bit heartier than “plain” green lentils, and I definitely agree. I simmered these in water for 20-25 minutes, and they still had a healthy bite, but they held together well too. I soaked my first batch for a few hours before I cooked them, and I really couldn’t tell a difference between not soaking at all.

When I cook lentils I love to use different veggies, and I pretty much always use onion, carrot, and garlic. So for the base of this burger, I used sauteéd onion and raw carrot.

I was going to add some garlic, but I realized I had some Texas Black Gold Garlic in the fridge. This garlic is grown in San Antonio and caramelized for 1-2 months in controlled heat and humidity. The result is umami and complex, with sweet and pungent notes that add depth of flavor.

I have started to use this puree in place of garlic in my cooking. It saves me a mince!

That sums up the wet ingredients of this burger, along with my seasonings:

  • French green lentils
  • sauteéd red onion
  • raw chopped carrot
  • Texas Black Gold garlic puree
  • unrefined salt
  • fresh black pepper
  • thyme – another lentil classic

Now, let us add dry ingredients to this delicious mix! To bind this patty, I added oyster mushroom powder and whole wheat breadcrumbs.

I got the Oyster Mushroom Powder

at the farmer’s market from Flying Saucer Farms. This dried and ground oyster mushroom provides another level of savory comfort to this burger.

The mushroom is complemented well by the right amount of unrefined salt. It’s still fairly warm in Houston, so we should continue to avoid salty dishes for the time being.

To make whole wheat bread crumbs:

I left some experimental burger buns in a brown bag for 3 days, cut crouton-sized pieces, baked in olive oil at 300º for 15-20 minutes, and food processed until fine.

Once I added these ingredients, the patties were forming well and holding together, so I took them to the grill!

Suggested Late Summer cooking method – sear and steam

I got a nice sear on these patties!

After I seared both sides, I added a bit of water to the pan and let the burgers steam. I think this helped the burgers to hold together better – and avoid a messy burger bite. I flipped them twice more after steaming.

On my last flip, I added some Follow Your Heart Smoked Gouda cheese.

Don’t get water on the bottom surface of the burger!

Now the exciting part, adding the toppings, and the taste test!

Mustard and Tomato: classic toppings done right

I was planning to do some mustard experiments, then I stumbled on a local mustard company here in Houston – Revival Provisions! I used their Old Faithful mustard on a burger, and it was so much more flavorful than the yellow mustard I had in my pantry. I wanted to hear more about their product, so I decided to reach out to them for a taste test!

Jacob and Aubry put a lot of care into their mustards!

Hear the recipes behind the three mustards we added to our burgers: Old Faithful, Jon Di Baptist, and Spicy Sinner

I really enjoy the flavors of these mustards.

  • Old Faithful is a classic yellow, but I could feel a healthy spice in my nose every few bites. Quite a bit of unapologetic flavor.
  • Jon Di Baptist is a spicy dijon made with rosé cider, tarragon, and shallots. Amazing flavors you can’t find anywhere else!
  • Spicy Sinner is a horseradish mustard made with local St. Arnold’s Guten Tag lager! Perfect for the Oktoberfest season.

I really can’t wait to try the rest of these mustards!

I haven’t tried Holy Spirit or The Sacrament yet!

BF Tomato Jam Batch #1

I had some Atkinson Farms tomatoes left from the Great Vegan Cook-off Vol. 3, and I made tomato jam. I used unrefined sugar, apple cider vinegar, cumin, coriander, cayenne, and allspice. Batch #1 was a success!

Use a thick layer of tomato jam on the bottom bun. You will notice pockets of sweet and spicy flavor as your burger disappears.

#2 will swap out the cumin for ginger/turmeric, and dried thai chili for cayenne.

What are your classic burger toppings?

I used verdegreens red butter leaf lettuce, tomato, red onion, and pickles.
