To make this pasta, start by preheating your oven to 425°F.
Cut the zucchini into 1-inch pieces and spread them onto a baking sheet. Lightly spray with your cooking oil of choice, then season with salt and pepper. Roast for 16 to 17 minutes, flipping once halfway through, until tender and lightly caramelized.
While the zucchini roasts, whisk together the cornstarch (or tapioca flour) with the water to create a slurry, then set it aside.
Cook your pasta according to the package instructions until al dente, then drain and set aside.
Next, make the sauce. Add the chicken broth, dark soy sauce, rice vinegar, maple syrup, tomato paste, ginger, gochujang, and garlic to a bowl and whisk until fully combined and smooth.
Lightly spray a large nonstick skillet with oil and add the ground beef. Use a masher to break it into small pieces as it cooks. Once the beef is about three-quarters of the way cooked through, pour in the sauce and stir until the meat is evenly coated. Add the cornstarch slurry and continue mixing for another minute, allowing the sauce to thicken.
Finally, add in the green onions, roasted zucchini, and cooked pasta. Toss everything together until fully coated in the sauce. Serve with extra green onions on top and sesame seeds, if desired. Enjoy!
