Cooking With Co-Op Basics:Beet & Zucchini Burgers
Makes 6 Burgers
Gluten Free Adaptable, Vegetarian
This recipe was adapted from one featured on The Kitchn and used for my August 2017 Cooking with Co-Op Basics class at Mississippi Market. It seems complicated but can be doubled or tripled and you can freeze the burgers for several months and save time later. This is a great weekend project recipe.
As with all my recipes, it is meant to be adapted for what is in season. See notes at the end of the recipe for variation ideas.
- 1/2 lb red beets $1.25
- 1/2 lb zucchini or summer squash $1.25

- 2 to 3 teaspoons smoked paprika, to taste $.25

- 1 teaspoon cumin $.20
- 1/2 teaspoon coriander $.20
- 1/2 teaspoon dried thyme $.20

- Note on cooking beans: Soak beans overnight in enough liquid to cover 3-4 inches above beans. Drain. Slow cook with enough water to cover by 2 inches until soft in the middle. This can be done on your stove top on a low boil/simmer for 2-3 hours. Consider cooking enough beans for multiple meals and freezing or refrigerating extra. Beans will keep 4-5 days in the refrigerator. Flavor with granulated garlic (2 tsp), dehydrated onion (1 Tbsp).
Bring a 2-quart pot of water to a boil. Salt the water generously and add the rice. Reduce the heat to a simmer and cook the rice until it's a little beyond al dente. You want it a little over-cooked, but still firm (not completely mushy). This should take about 35 to 40 minutes. Drain the rice and set it aside to cool.
While rice is cooking, peel and grate beets into a colander in a bowl (careful of spraying juice on your clothes and surroundings). Press and squeeze the beet gratings to remove as much liquid as possible from the beets (reserve liquid for drinking or soup!)
Grate your summer squash next and begin sautéing with the onion. Heat a teaspoon of olive oil in a skillet over medium-high heat. Add the onions and a pinch of salt. Stir the onions every minute or two, adding squash when the onions are soft and starting to brown. Cook until they are golden and getting charred around the edges, 10 to 12 minutes. A few wisps of smoke as you are cooking are OK, but if it seems like the onions are burning, lower the heat. A dark, sticky crust should develop on the bottom of the pan
Add the garlic and cook about 10 seconds. Pour in the cider vinegar and scrape up the dark sticky crust. Continue to simmer until the cider has evaporated and the pan is nearly dry again. Remove from heat and set aside to cool. Using the same pan, start to saute the beets in 1 Tbsp of oil, covering to let steam for the first few minutes. Stir every minute or two and remove from heat when soft.
Process the oats in a food processor or blender until they have reduced to a fine flour. Transfer to a small bowl and set aside. (if you have oat flour at home you can use 1/4 cup).
Pulse 1.5 cup beans and prunes in 1-second bursts just until the beans are roughly chopped — not so long that they become mush — 8 to 10 pulses. Transfer this mixture to a large mixing bowl. Add remaining 1.5 cups whole beans to the mixing bowl as well.
Transfer the beets, cooked rice, and sautéed squash & onions to the bowl with the beans. Sprinkle the olive oil, mustard, 2 teaspoons of smoked paprika, cumin, coriander, and thyme over the top of the mixture. Mix all the ingredients until combined. Taste the mixture and add salt, pepper, or any additional spices or flavorings to taste. Finally, add the oatmeal flour and egg (if using — it helps hold everything together, but isn't 100% necessary), and mix until you no longer see any dry oatmeal or egg.
Refrigerate the burger mixture for at least 2 hours or (ideally) overnight. The mix can also be kept refrigerated for up to three days before cooking.
When ready to cook the burgers, first shape them into 6 large patties.
Cook the burgers: Heat a cast iron skillet over high heat. Add a few tablespoons of vegetable oil to completely coat the bottom of the pan. When you see the oil shimmer and a flick of water evaporates on contact, the pan is ready.
Cook the patties for 2 minutes, then flip them to the other side. You should see a nice crust on the cooked side. If any pieces break off when you flip the burgers, just pat them back into place with the spatula. Cook for another 2 minutes, then cover the pan and reduce the heat to medium-low. Cook for 4 more minutes until the patties are warmed through.
Notes & Variations:
Adaptations: Feel free to substitute squash, sweet potato, or carrots for beets. If adding greens or zucchini, cook with onions. Substitute spices to be Italian or Mediterranean seasoning if preferred and use white beans or garbanzo beans. If your budget allows, consider topping with whipped feta and yogurt mixed together, fresh tomato/onion/lettuce, or other preferred toppings.
Freezing Burgers: Burgers can be frozen raw or cooked. Wrap each burger individually in plastic or between sheets of parchment paper, and freeze. Raw burgers are best if thawed in the fridge overnight before cooking. Cooked burgers can be reheated in the oven, a toaster oven, or the microwave.
