Cooking Steps
• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Cut sweet potatoes into ¼-inch-thick wedges. Toss sweet potatoes on a baking sheet with a large drizzle of oil, salt, and pepper. Roast on top rack until browned and tender, 20-25 minutes.
• Meanwhile, trim scallions and cut greens into 1-inch pieces; mince whites. Peel and mince or grate garlic. Halve buns. Slice cucumber into ¼-inch-thick rounds. • In a small bowl, combine mayonnaise, sour cream, 1 tsp soy sauce (2 tsp for 4 servings), ¼ tsp sugar (½ tsp for 4), and Sriracha to taste. (Be sure to measure the soy sauce—we sent more.)
• Heat a large drizzle of oil in a large pan over medium-high heat. Add scallion greens and cook, stirring occasionally, until slightly charred and fragrant, 2-4 minutes. • Add garlic and cook, stirring, until fragrant, 1 minute more. • Turn off heat; transfer scallion mixture (including oil!) to a large bowl and season with salt and pepper. Wipe out pan.
• In a second large bowl, combine beef*, scallion whites, and half the Fry Seasoning (all for 4 servings). Form into two patties (four patties for 4), each slightly larger than a burger bun. Season generously with salt and pepper. • Heat a drizzle of oil in pan used for scallions over medium-high heat. Add patties and cook to desired doneness, 3-5 minutes per side.
• While patties cook, toast buns until golden brown. • Transfer sweet potatoes to bowl with scallion mixture; toss to combine. Taste and season with salt and pepper if desired.
• Spread cut sides of bottom buns with as much sauce as you like. Fill buns with patties, cucumber, and more sauce if desired. Serve with sweet potatoes and any remaining sauce on the side for dipping.
Ground Beef is fully cooked when internal temperature reaches 160°.

Reviews from our home cooks
Great I added extra garlic cause I always keep some on hand as I love it so much. This was great I wasn't sure about it but it was good. Cucumbers on a burger who knew. I do think the soy was too much for my tasting I added more Mayo and sour cream I had from the fridge. I would recommend just adding the soy to taste- start with a little then add more if you'd like. I wish I had done that. But otherwise a great meal.
The firecracker sauce is really good, especially with the cucumbers as contrast, and I love anything that includes sweet potatoes. I wouldn't mind more variety in the types of buns though (like wholegrain variations, pitas, ciabattas and other breads).
The burger was good, but wasn't spicy and was a little bland, I ended up adding chopped habaneros to the beef instead of the scallions. The fries were the main attraction. I will always cook sweet potato fries like this.
I loved the sriracha garlic sauce and it never would have occurred to me to put cucumbers on a hamburger. I liked it.
We really enjoyed this meal. I was very surprised at how much I enjoyed it. I wasn't sure I'd like putting cucumbers on my burger but I tried it and really enjoyed it!
Loved the cucumber accent. And the sweet potato fries were way better than regular potatoes. Great combo.
Liked the spicy flavor, wish it had a little more kick. Maybe add some kind of pepper in the burger meat? I loved the sweet potato side, but husband wasn't super fond of it.
This was pretty good overall but I think raw cucumber overwhelmed pretty much every other flavor. I got a tiny bit of heat from the sauce (used all the Sriracha) but overall it got lost on the burger. The sweet potatoes though were AMAZING
These Were Excellent, Would Try Again. I'm A Huge Fan Of A Hint Of Spice That Leaves Flavor On Your Tongue, Not Fire.
Never had cucumbers on a burger before, but it was super good. Meat did not hold together well. Suggest adding another ingredient to make the patties stick together better.
