Prepare the Sweet Potatoes: Preheat your oven to 425°F (220°C). To make cleanup easier after cooking, cover a large baking sheet with parchment paper before starting. Cut the sweet potatoes into thin strips resembling fries. For extra-crunchy fries, immerse the cut potatoes in cold water for half an hour. Afterward, thoroughly dry them using paper towels. Toss the sweet potatoes in olive oil, paprika, garlic powder, onion powder, salt, and pepper. Spread them evenly on the baking sheet without overlapping. Cook the fries for 30 to 35 minutes, turning them over midway through the process until they achieve a golden-brown color and crispy texture.
Cook the Ground Beef: Place a large skillet on the stove and set it to medium-high heat. Pour in some olive oil and allow it to warm up. When the oil is sufficiently heated, introduce the ground beef to the pan. Sprinkle smoked paprika, dried oregano, garlic powder, onion powder, salt, and pepper over the meat. While the beef is cooking, utilize a wooden utensil to stir and separate the meat into small pieces. Mix the meat intermittently as it cooks, continuing until it turns brown and is thoroughly cooked. The completion of this procedure usually requires approximately 6 to 8 minutes. Once completed, remove from heat and maintain warmth.
Prepare the Special Sauce: Combine mayonnaise, ketchup, Dijon mustard, pickle brine, smoked paprika, garlic powder, salt, and pepper in a small container. Mix the components vigorously to achieve a well-combined mixture. Taste the resulting blend and adjust the spices as needed. Cover and refrigerate until ready to serve.
Assemble the Burger Bowls: Divide the romaine lettuce evenly among four bowls as the base. Top each bowl with cooked ground beef, roasted sweet potato fries, halved cherry tomatoes, dill pickles, shredded cheddar cheese (if using), and thinly sliced red onions. Liberally apply the signature dressing over each serving and present without delay.
