How To Cook Rice Noodles (Without Overcooking Them!)

Rice noodles are a pantry staple in my kitchen. They’re light, versatile, and cook fast—but they can also go wrong fast.

Overcook them and they turn mushy. Undercook them and they’re stiff and unpleasant. Once you know how to handle them, though, rice noodles are one of the easiest noodles to work with.

In this post, I’ll walk you through the different types of rice noodles and exactly how to cook each one, whether you’re using dried or fresh. I’ll also share practical tips I use every time to keep them from clumping or turning soggy.

What Are Rice Noodles?

Rice noodles are made from rice flour and water. Some brands add tapioca or cornstarch for extra chew.

They’re naturally gluten-free and come in a range of shapes and widths—from super thin vermicelli to wide flat noodles used in soups and stir-fries. Each type behaves a little differently, which is why cooking them the right way matters.

Matching the noodle to the dish makes a huge difference in texture.

Types of Rice Noodles

Vermicelli (Bún)

These are thin, round rice noodles commonly used in dishes like grilled pork noodle bowl (bun thit nuong), and crab and tomato noodle soup (bun rieu). They’re also often used in smaller amounts inside fillings for Vietnamese egg rolls (cha gio) or meat pastries (pate chaud).

They’re soft, springy, and cook very quickly, which also means they can overcook easily if you’re not watching them.

Dried Flat Rice Noodles (Phở)

Often labeled as rice stick noodles, these flat noodles come in several widths. The size you choose matters—it affects both texture and how the noodles hold up in the dish.

• Small (2mm): Most commonly used in soups like Vietnamese pho, including pho tai and Instant Pot pho.
• Medium (3mm): A good all-purpose size that works for soups and stir-fried dishes like pad Thai.
• Large (5mm) and Extra Large (10mm): Best for stir-fries where you want chewy noodles that won’t break apart, such as pad see ew, beef chow fun, or hu tieu xao

Fresh Rice Noodles

These are usually found refrigerated at Asian grocery stores. They’re soft, pliable, and often already cooked.

They’re great for quick stir-fries or soups when you want minimal prep.

How to Cook Vermicelli (Bún)

Rice vermicelli should always be soaked before boiling. You’ll know they’re ready when they bend easily without snapping.

Soaking and cooking time can vary slightly by brand, but this method works consistently.

1. Soak rice vermicelli in cold water for 30 minutes.
2. Separate the noodles, then cook in boiling water for 30 seconds to 1 minute, just until tender.
3. Drain and rinse under cold water, gently separating with your hands.

Tip: Vermicelli goes from perfect to mushy very fast. Err on the side of undercooking.

If serving with rice paper or hot pot, portion the noodles into small bundles and cut them into manageable lengths to prevent clumping.

How to Cook Dried Rice Stick Noodles

Like vermicelli, dried flat rice noodles need to be soaked before cooking. They’re ready when they bend without feeling brittle.

Thin Rice Noodles

• Soak in cold water for 1 hour or lukewarm water for 30 minutes
• Place one portion in a strainer and dip into boiling water for 20–30 seconds
• Transfer directly to a serving plate or bowl

Thick Rice Noodles

• Soak in hot water (140–160°F) for 12–15 minutes
• Drain well and rinse with cold water before serving

Tip: Always check the package instructions—brands vary more than you’d expect.

How to Cook Fresh Rice Noodles

Fresh rice noodles cook quickly since they’re already soft.

1. Place one portion in a strainer and dip into boiling water for 15–20 seconds
   (Thicker noodles may need up to 1–2 minutes.)
2. Rinse under cold running water to stop the cooking and remove excess starch.
3. Transfer to a serving bowl or add directly to your dish.
