No, traditional rice noodles are too high in carbs for keto; use low-carb swaps like shirataki or kelp noodles instead.
Here’s the straight answer up front: classic rice noodles pack enough starch to blow past a typical keto carb budget. That doesn’t mean you have to give up noodle bowls. With the right swaps and sauces, you can keep the slurp and stay in ketosis.
What Keto Means For Carbs
Keto works by driving your daily carbs low enough that your body makes ketones for fuel. Most plans land between 20–50 grams of carbs per day, sometimes even tighter early on. Harvard Health carb range outlines this span and sets a clear guardrail when you’re aiming for ketosis.
Can You Have Rice Noodles On The Keto Diet?
Short answer: no. A single cup of cooked rice noodles delivers roughly 42 grams of carbs, about 40 grams of net carbs. That’s nearly a whole day’s allotment in one bowl. Those figures come from lab-sourced nutrient data aggregated by MyFoodData, which compiles USDA FoodData Central numbers. Rice noodles, cooked — nutrition.
Rice Noodles Vs Keto At A Glance
The snapshot below compares rice noodles with popular keto-friendly “noodle” bases so you can choose what fits your day.
| Food | Typical Serving | Net Carbs (g) |
|---|---|---|
| Rice noodles (cooked) | 1 cup (175 g) | ~40 |
| Shirataki (konjac) | 100 g | ~0 |
| Kelp noodles (Sea Tangle) | 113 g | ~2 |
| Hearts of palm pasta | 85 g | ~2 |
| Zucchini “zoodles” | 1 cup | ~2–3 |
| Spaghetti squash strands | 1 cup (155 g) | ~7–8 |
| Cabbage ribbons | 1 cup sautéed | ~3–4 |
Why Rice Noodles Miss The Keto Cutoff
Starch Density
Rice flour is mostly starch. Once cooked, those noodles carry little fiber and a big carb load, so the “net” number stays high. In a standard portion you’ll see around 41.8 grams of total carbs and only about 1.8 grams of fiber, which leaves roughly 40 grams of net carbs — enough to stall ketone production for many people.
“But What If I Just Have A Few Bites?”
You can budget anything, but the math is tight. Two heaping forkfuls can add up fast, and sauces with sugar or starch thickeners stack more carbs onto the plate. If you truly want the taste, mix a small handful of rice noodles into a larger bed of kelp or shirataki and measure the portion with a scale. Even then, keep it for rare occasions.
Rice Noodles On Keto Diet Rules: What Works Instead
You can still build steaming bowls, stir-fries, and cold sesame “noodles” that feel like the real thing. These bases do the heavy lifting:
Shirataki (Konjac) Noodles
Made from the konjac root’s glucomannan fiber, shirataki brings near-zero net carbs and almost no calories. A 100-gram portion sits around 9 calories with roughly 2.7 grams of fiber against similar total carbs, which nets to about zero. That’s why they’re a staple for low-carb cooks.
Prep tip: drain, rinse for 60 seconds, then dry-fry in a hot nonstick pan for 2–3 minutes before saucing. That quick dry-fry improves bite and helps sauces cling.
Kelp Noodles
These seaweed-based strands are springy and glass-clear. A 113-gram serving lands near 3 grams of carbs and 1 gram of fiber (about 2 grams net), with only 6 calories. Quick soak in hot water with a squeeze of lemon or a pinch of baking soda to soften, then toss into broths or peanut-style sauces.
Hearts Of Palm Pasta
Cut from the core of palm, this pasta holds up nicely in skillet sauces. A typical 85-gram serving runs about 4 grams total carbs with 2 grams of fiber (around 2 grams net). It tastes faintly like artichoke, which pairs well with garlic, olive oil, and lemon.
Zucchini “Zoodles”
Fresh spiralized zucchini gives a clean, neutral base with about 2–3 grams of net carbs per cup. Sweat the strands in a hot pan for a minute to drive off moisture; saucing after that keeps the texture firm.
Spaghetti Squash
Bake, shred, and you’ve got golden strands that hold pesto or meat sauce well. One cup sits near 9.7 grams total carbs with 2.2 grams of fiber, or about 7–8 grams net.
Portion Math: Keep Ketosis On Track
Think of your daily cap as a small wallet. If your target is 30 grams net, one cup of rice noodles would spend that entire wallet at lunch. Use this quick guide to budget bowls and still eat well.
| Craving | Low-Carb Base | Example Net Carbs |
|---|---|---|
| “Pho” night | Kelp noodles in beef broth | ~2 g (noodles only) |
| Sesame “lo mein” | Shirataki tossed in tahini/soy | ~0–1 g (noodles only) |
| Chicken soup | Zucchini ribbons | ~2–3 g per cup |
| Garlic butter “pasta” | Hearts of palm fettuccine | ~2 g per 85 g |
| Pesto bowl | Spaghetti squash | ~7–8 g per cup |
| Cold peanut “noodles” | Shirataki or kelp | ~0–2 g |
| Ramen-style | Shirataki in miso broth | ~0–1 g (noodles only) |
Build Better Keto Noodle Bowls
Balance The Plate
Keep protein steady, add non-starchy veggies for volume, and use fats for flavor. Broth bowls drink up sliced beef, chicken thighs, eggs, tofu, bok choy, mushrooms, and scallions.
Sauce Smart
Thickeners and sugars add carbs fast. Choose soy sauce or tamari, rice vinegar, chili oil, sesame oil, garlic, ginger, and zero-sugar sweeteners. For creamy sauces, whip cream cheese with parmesan and a splash from the shirataki dry-fry to help it cling.
Seasoning Moves
Toast aromatics in oil first, then add noodles. Finish with acid (lime, rice vinegar) and a quick hit of toasted sesame seeds. That last splash brightens flavors and cuts any kelp or konjac aroma.
Label Check: Spot Hidden Carbs
Packaged “rice noodle” cups often include sugar, starches, and corn syrup solids. If a brand lists tapioca, potato starch, or dextrins near the top, the net carbs will spike. Aim for shirataki with water, konjac flour, and calcium hydroxide; kelp noodles with water, kelp, and sodium alginate; hearts of palm with simple brine.
When A Rice Noodle Craving Hits
If you’re set on the taste of rice noodles, make a tiny blend. Combine 30–40 grams of cooked rice noodles with a full serving of shirataki. You’ll get the chew you want and keep total net carbs in single digits. It’s still a splurge, so plan the rest of the day around it.
Takeaways You Can Use Tonight
- The phrase “Can You Have Rice Noodles On The Keto Diet?” points to carbs, not gluten. The hurdle is starch load, not wheat.
- One cup of cooked rice noodles is about 40 grams net carbs — that’s the whole day for many keto eaters.
- Use shirataki, kelp noodles, hearts of palm, zucchini, or spaghetti squash to stay under your target.
- Keep sauces simple, add acid at the end, and portion protein and veggies generously.
- If you mix a touch of rice noodles into a keto base, measure the grams cooked and track it.

Final Answer To The Question: Can You Have Rice Noodles On The Keto Diet?
No — rice noodles aren’t keto-friendly in standard portions. If you want noodle nights while staying in ketosis, pick shirataki, kelp, hearts of palm, zucchini, or spaghetti squash, keep sauces low in sugar and starch, and portion with intention.
