📋 Ingredients You’ll Need
- 🥩 1 lb lean ground beef
- 🧅 ½ onion, chopped
- 🫑 ½ red bell pepper, sliced
- 🫑 ½ orange bell pepper, sliced
- 🌿 3 tbsp olive oil
- 🍜 1 can (12 oz) Palmini noodles, rinsed & well-drained
- 🧄 2 tsp minced garlic
- 🫚 2 tsp ginger paste
- 🥣 1 tbsp oyster sauce
- 🪵 1 tbsp Swerve brown sugar substitute
- 🧉 1 tsp sesame oil
- 🍲 2 tbsp beef broth
- 🧉 2 tbsp low-sodium soy sauce (or coconut aminos)
- 🌱 ¼ cup green onions, chopped (for garnish)
🍳 How to Make Keto Beef Lo Mein (Step-by-Step)
- Sizzle the beef & veggies: Heat olive oil in a large skillet over medium-high heat. Add the ground beef, chopped onion, and sliced bell peppers. Cook until beef is nicely browned and veggies are tender-crisp (about 5–6 minutes). Carefully drain any excess grease.
- Whisk the flavor bomb: In a small bowl, whisk together soy sauce, beef broth, sesame oil, Swerve brown sweetener, oyster sauce, minced garlic, and ginger paste until smooth and the sweetener dissolves.
- Add the “noodles”: Toss the rinsed and drained Palmini noodles directly into the skillet with the beef mixture. Stir to combine.
- Pour & coat: Pour the savory sauce evenly over the beef and noodles. Use tongs or a spatula to toss everything together, making sure every strand is beautifully coated.
- Simmer to perfection: Sauté for about 5 minutes over medium heat, stirring occasionally, so the Palmini noodles soak up all that rich, umami flavor. The noodles will become tender but not mushy.
- Finish & serve: Remove from heat, garnish generously with fresh green onions, and serve hot. Pro tip: add a sprinkle of sesame seeds for extra flair!
🎨 5 Fun Ways to Serve This Keto Beef Lo Mein
- 🥢 Classic Bowl: Pile it high in a deep bowl, top with extra green onions and a drizzle of chili oil (if you like heat).
- 🥗 Lettuce Wraps: Spoon the lo mein into crisp butter lettuce cups for a crunchy, portable keto taco experience.
- 🍳 Fried Egg Topper: Slide a sunny-side-up egg right on top — the runny yolk makes everything extra luxurious.
- 🥒 Zoodle Mix: Add a handful of spiralized zucchini while sautéing for even more veggie bulk and color.
- 🫘 Spicy Peanut Twist: Stir in 1 tbsp sugar-free peanut butter and a pinch of red pepper flakes for a Thai-inspired version.
📦 How to Store & How Long It Lasts
Refrigerator: Store leftovers in an airtight container for up to 4 days. The Palmini noodles hold up really well — they don’t get mushy like regular noodles.
Freezer: Freeze in a sealed container for up to 2 months. Thaw overnight in the fridge. Reheat in a skillet with a splash of beef broth to revive the sauce.
❄️ Reheating tip: Microwave in 30-second bursts, or warm in a pan over medium heat for 3–4 minutes. Add a tiny bit of water if the sauce seems too thick.

7. Why are my noodles watery?
Palmini can release water if not drained thoroughly. After rinsing, pat them dry with a paper towel. Also, make sure your skillet is hot before adding noodles.
