Ingredients with Measurements
- 1 1/2 lbs fresh zucchini (about 2 medium)
- 1/4 tsp salt
- 1/4 cup tamari (gluten-free soy sauce)
- 3 tbsp Swerve Brown sweetener
- 2 tbsp allulose (or preferred keto sweetener)
- 1 tbsp sesame oil
- 2 tsp sriracha (optional, for a spicy kick)
- 2 tsp freshly grated ginger
- 2 cloves garlic, minced
- 1/4 tsp red pepper flakes
- 2 tbsp coconut oil
- 1 1/3 lbs lean ground beef (85/15 works great)
- 1 medium green onion, thinly sliced
- 1 tsp toasted sesame seeds
Detailed Step-by-Step Directions
- Prep the veggie noodles: Spiralize your zucchini into noodles, then give them a few quick chops so they’re easier to eat. Place them in a colander, sprinkle with salt, and let drain for 1 hour to release excess water. Pat them completely dry between clean kitchen towels without squeezing—this is key for perfect texture.
- Mix the healthy sauce: In a small bowl or measuring cup, whisk together tamari, Swerve Brown, allulose, sesame oil, sriracha, ginger, garlic, and red pepper flakes. Set aside.
- Brown the beef: Heat coconut oil in a large skillet over medium heat. Add ground beef and cook about 7 minutes, breaking up chunks with a spoon, until nicely browned and cooked through.
- Simmer and coat: Pour the prepared sauce and sliced green onions into the skillet with the beef. Cook 2–3 minutes, letting the sauce simmer, reduce, and glaze the meat. You’ll see it become glossy and irresistible.
- Toss and serve: Add dried zucchini noodles to the skillet. Gently toss everything together for 2–3 minutes just to warm the noodles through—don’t overcook or they’ll release water. Garnish with toasted sesame seeds and enjoy immediately.
Different Ways to Present & Serve
Bowl style: Serve the Keto Korean Beef with Zucchini Noodles in a shallow bowl, topped with extra sliced green onion, a drizzle of sriracha, and a sprinkle of chili flakes. Add a soft-boiled egg on the side for extra richness.
Over cauliflower rice: For a heartier base, spiralized zucchini noodles can be swapped or combined with cauliflower rice. The beef and sauce are delicious spooned over a bed of fluffy riced cauliflower.
As lettuce wraps: Turn this into an appetizer or fun dinner by spooning the beef mixture into large butter lettuce leaves, then topping with the zucchini noodles and sesame seeds. Perfect for parties or meal prep.
Grain-free noodle mix: Mix with shirataki noodles or kelp noodles for extra texture. Just be sure to rinse and dry them well before adding to the skillet.
How You Can Store It & How Long It Lasts
Store any leftovers in an airtight container in the refrigerator. The Keto Korean Beef with Zucchini Noodles will stay fresh for up to 3 days. Keep the beef and noodles separate if possible—the noodles can release moisture over time. If already combined, simply reheat gently in a skillet over medium-low heat for 2–3 minutes, or in the microwave in 30-second bursts. Do not freeze, as zucchini noodles become mushy upon thawing.
FAQs – 10 Questions
- Can I use regular soy sauce instead of tamari? Yes, but tamari is gluten-free and has a cleaner taste. Regular soy sauce works, but the dish won’t be gluten-free.
- What can I substitute for Swerve Brown? Any brown keto sweetener (e.g., Lakanto Golden) or use regular erythritol with a drop of molasses for color. Allulose helps with a syrupy texture.
- Is sriracha keto-friendly? Most brands have a tiny amount of sugar, but 2 tsp per entire recipe is negligible for net carbs (less than 1g per serving).
- Can I skip the allulose? Yes, but the sauce may not thicken as well. You can replace it with additional Swerve or a few drops of liquid stevia.
- Why do I need to salt and dry the zucchini? Salting draws out water, preventing soggy noodles. Drying ensures they don’t steam in the skillet.
- Can I use pre-spiralized zucchini from the store? Absolutely, but still salt and dry them as directed—even pre-packaged noodles release a lot of water.
- What other protein can I use? Ground chicken, turkey, or even crumbled tofu work perfectly. Adjust cook time as needed.
- How do I make it spicier? Increase sriracha to 1 tbsp, add extra red pepper flakes, or toss in sliced fresh chili when cooking the beef.
- Can I prepare the noodles ahead of time? Yes. Spiralize, salt, dry, then store in a sealed zip bag in the fridge for up to 2 days. Toss with a little oil before cooking.
- Is this recipe Whole30 compliant? With tamari (or coconut aminos), yes. Use compliant sweeteners or skip them, and omit sriracha if needed.
