35-Minute Keto Bulgogi Zoodle Stir Fry

Ever crave those bold, sweet-savory flavors of Korean bulgogi but need to keep it low-carb? That’s exactly how I landed on this keto bulgogi zoodle stir fry—my go-to when I want something indulgent yet totally guilt-free. Trust me, the first time I made it, my family didn’t even miss the rice! The magic comes from that rich marinade clinging to tender beef, paired with fresh zucchini noodles that soak up all the goodness without weighing you down. It’s the kind of dish that proves keto doesn’t mean sacrificing flavor—just ask my spice-loving dad, who now requests it weekly.

Why You’ll Love This Keto Bulgogi Zoodle Stir Fry

This isn’t just another stir fry—it’s your new secret weapon for busy weeknights when you want something spectacular without the carb crash. Here’s why I’m obsessed:

• Weeknight magic: From fridge to table in 35 minutes flat (20 of those are hands-off marinating time!)
• Flavor bomb: That caramelized, garlicky marinade tastes like you spent hours in the kitchen—my Korean aunt actually thought I cheated and ordered takeout
• No sad diet food: The zucchini noodles stay perfectly al dente, soaking up the sauce while keeping that satisfying bite
• Meal prep hero: Tastes even better the next day—I always double the batch for lunches
• Customizable heat: Start with 1 tbsp gochujang, then add more if you’re feeling brave (I learned that lesson after making my eyes water!)

Seriously, this dish converted my carb-loving husband to the keto dark side—and that’s saying something.

Ingredients for Keto Bulgogi Zoodle Stir Fry

Okay, here’s where we get specific! I’ve made this enough times to know that quality here makes all the difference. Don’t worry, it’s all simple stuff you can find at any grocery store. Here’s your shopping list:

• 1 lb beef sirloin, thinly sliced – This is key! Get it as thin as you can. I sometimes pop it in the freezer for 15 minutes first to make slicing easier. You can also use flank steak.
• 4 medium zucchinis, spiralized – About 6-7 inches long each. I’ll show you my trick to avoid soggy zoodles later!
• 3 tbsp soy sauce – For a gluten-free version, swap this with coconut aminos. It works just as well and is a bit sweeter.
• 2 tbsp erythritol – This is my go-to keto sweetener for bulgogi. Monk fruit or allulose work great too.
• 2 cloves garlic, minced – Fresh is best here, trust me. None of that jarred stuff!
• 1 tbsp sesame oil – The toasted kind, for that authentic flavor.
• 1 tbsp grated ginger – Again, fresh! I keep a knob in the freezer and just grate what I need.
• 1 tbsp gochujang (optional) – This is the Korean chili paste. Start with 1 tsp if you’re sensitive to heat!
• 2 green onions, sliced – For garnish, but they add such a fresh crunch.
• 1 tbsp sesame seeds – Toasted if you have time.
• 1 tbsp avocado oil – For cooking. Any high-heat oil works.

That’s it! See? Nothing crazy. Now let’s make some magic.

How to Make Keto Bulgogi Zoodle Stir Fry

Alright, let’s get cooking! This comes together so fast you’ll barely believe it—just follow these steps and you’ll have restaurant-worthy bulgogi zoodles in no time.

Preparing the Bulgogi Marinade

First, grab that big mixing bowl—this is where the flavor magic happens. I like to whisk together the soy sauce (or coconut aminos if you’re going gluten-free) with the erythritol until the sweetener dissolves completely. Pro tip: If your sweetener is granulated, give it a quick pulse in a spice grinder first so it blends smoothly.

Next, mince those garlic cloves—I press mine with the flat of my knife first to release all those aromatic oils. Grate the ginger too (no need to peel it if you’re using fresh!). The sesame oil and gochujang go in last—start with half the chili paste if you’re nervous about heat. Taste as you go—it should be sweet, salty, and just a little spicy.

Now toss in your thinly sliced beef, making sure every piece gets coated. I use my hands for this part—messy, but effective! Let it marinate while you prep the zoodles (about 20 minutes is perfect). Any longer and the acidity starts to “cook” the beef.

Cooking the Beef and Zoodles

Heat your largest skillet or wok over medium-high heat—I swear by my cast iron for this. Add the avocado oil and wait until it shimmers (about 30 seconds). Carefully add the beef in a single layer—you might need to work in batches to avoid steaming. Listen for that satisfying sizzle!

Don’t touch it for a full minute—this builds that gorgeous caramelization. Then stir-fry for another 2-3 minutes until the beef is browned but still juicy. Transfer it to a plate—it’ll keep cooking slightly from residual heat.

In the same pan (those browned bits are flavor gold!), add the zoodles. Stir-fry them for just 2-3 minutes—you want them tender-crisp, not mushy. They’ll release water, so crank the heat to high for the last 30 seconds to evaporate excess moisture. Toss the beef back in, sprinkle with green onions and sesame seeds, and serve immediately. That smell? Pure happiness.

Tips for Perfect Keto Bulgogi Zoodle Stir Fry

After making this dish dozens of times (and learning from my mistakes!), here are my can’t-live-without tips:

• Dry those zoodles: After spiralizing, pat them dry with paper towels—wet noodles = soggy stir fry. I sometimes salt them lightly and let them drain in a colander for 10 minutes.
• Hot pan, fast cook: That high heat is crucial for the beef to caramelize without stewing in its juices. If your beef starts releasing liquid, your pan wasn’t hot enough!
• Taste your marinade: Adjust sweetness or spice before adding the beef. Remember, the flavors mellow slightly when cooked.
• Don’t crowd the pan: Cook the beef in batches if needed. Overcrowding steams instead of sears.
• Zoodles last: They only need 2-3 minutes max—any longer and they turn mushy. I set a timer!

Bonus: Leftover marinade? Brush it on grilled chicken or tofu—it’s too good to waste!

Ingredient Substitutions for Keto Bulgogi Zoodle Stir Fry

Life happens—maybe you’re out of soy sauce or someone at the table can’t handle spice. No worries! Here are my tried-and-true swaps that keep this dish keto without sacrificing flavor:

• No soy sauce? Coconut aminos work beautifully (and add a touch more sweetness). For a soy-free option, try 2 tbsp tamari mixed with 1 tbsp water.
• Out of erythritol? Monk fruit or allulose blend in seamlessly. If using powdered stevia, start with 1 tsp—it’s much sweeter!
• Not a beef fan? Thinly sliced chicken thighs or even portobello mushrooms soak up the marinade wonderfully (just reduce cooking time by 1-2 minutes).
• Can’t find gochujang? Mix 1 tsp red pepper flakes with 1/2 tsp tomato paste for a quick fix. Or skip it entirely—the dish still tastes amazing.
• No spiralizer? Use a vegetable peeler to make wide zucchini ribbons—they’ll still grab all that saucy goodness!

See? Flexibility is the name of the game here. The only rule? Don’t skimp on the garlic and ginger—they’re non-negotiable!

Serving Suggestions for Keto Bulgogi Zoodle Stir Fry

Now for the fun part—how to make this dish feel like a complete Korean feast! My family loves building little keto-friendly “banchan” plates around the stir fry. Here’s what we always include:

• Kimchi: That tangy crunch cuts through the richness perfectly. I grab the refrigerated kind—it’s got more probiotics!
• Quick-pickled cucumbers: Just toss sliced cukes with rice vinegar, erythritol, and sesame seeds. They’re ready in 10 minutes.
• Cauliflower rice: For my rice-loving friends, I sauté riced cauliflower with a splash of sesame oil—it fools everyone.
• Soft lettuce cups: Butter lettuce makes perfect little wraps for the beef and zoodles.
• Extra chili flakes: For my heat-seeking brother who claims “it’s not spicy enough” (eye roll).

Pro tip: Serve everything family-style with small bowls—it makes the meal feel extra special. And don’t forget extra sesame seeds for sprinkling!

Storing and Reheating Keto Bulgogi Zoodle Stir Fry

Here’s the good news—this dish tastes even better the next day as the flavors meld! Store leftovers in an airtight container in the fridge for up to 3 days. The zoodles will soften slightly, but I actually love the extra sauce absorption. For freezing (up to 2 months), pack just the beef portion—thaw overnight in the fridge before reheating.

When reheating, skip the microwave if you can! I toss everything in a hot skillet for 2-3 minutes to revive that crisp-tender texture. Add a splash of water or broth if it looks dry. Pro tip: If your zoodles got too soft, mix in fresh ones at the end—they’ll soak up the sauce while staying crisp.

Frequently Asked Questions About Keto Bulgogi Zoodle Stir Fry

I’ve gotten so many questions about this recipe since I started sharing it—here are the ones that pop up most often with my tried-and-true answers:

Can I use chicken instead of beef?
Absolutely! Thinly sliced chicken thighs work best—they stay juicier than breasts. Marinate the same way but reduce cooking time to 2-3 minutes per side. Bonus: chicken soaks up that marinade like a dream!

How can I reduce the sodium?
Easy—swap regular soy sauce for low-sodium versions or coconut aminos (which have about 1/3 less sodium). You can also halve the soy sauce and add 1 tbsp fish sauce for depth without as much saltiness.

My zoodles turned out watery—what went wrong?
Ah, the soggy zoodle struggle! Always pat them dry after spiralizing, and don’t overcook—2-3 minutes max in the pan. If they still release too much liquid, try salting them for 10 minutes then squeezing out excess water before cooking.

Can I meal prep this?
You bet! Cook the beef and sauce separately from the zoodles. Store them apart in the fridge—when ready to eat, quickly sauté fresh zoodles (1 minute!) then mix with reheated beef. The texture stays perfect this way.

Is gochujang keto-friendly?
Surprisingly yes! Most brands have about 2g net carbs per tablespoon. Just check labels—some add sugar. My trick? Mix 1 tsp chili powder with 1/2 tsp tomato paste if you’re watching carbs closely.
