Vietnamese Omelette Recipe With Rice Flour

This Vietnamese-style omelette combines eggs, rice flour, fish sauce, shallot, and scallions for a savory, tender center with lightly crisp edges. It takes inspiration from everyday Vietnamese trứng chiên, or fried omelette, while the rice flour is a useful variation rather than a defining ingredient in every version.

Ingredients

5 large eggs
2 tablespoons plain rice flour (16 g), not glutinous rice flour
2 tablespoons water (30 ml)
2 teaspoons fish sauce (10 ml)
1 tablespoon finely minced shallot (10 g)
2 scallions (20 g), thinly sliced
¼ teaspoon ground black pepper (0.5 g)
2 teaspoons neutral cooking oil (10 ml), such as canola or sunflower oil
1 cup loosely packed fresh herbs (about 15 g), such as cilantro, mint, or Thai basil, for serving
1 small cucumber (about 200 g), thinly sliced, for serving
1 lime, cut into wedges, for serving

Instructions

Prepare the rice flour mixture. In a medium bowl, whisk the rice flour with the water until smooth. Scrape the sides and bottom of the bowl so no dry pockets remain. Let the mixture stand while you slice the scallions and mince the shallot; this brief pause lets the flour absorb water and makes it easier to blend evenly into the eggs. If the slurry thickens, whisk it again before continuing.
Season the eggs. Crack the eggs into the bowl with the rice flour mixture. Add the fish sauce and black pepper, then whisk until the yolks and whites are fully combined and the batter looks uniform. Stir in the shallot and most of the scallions, reserving a pinch for the top if you like. Whisking thoroughly matters: it distributes the flour and seasoning so the finished omelette does not have a floury patch or an overly salty bite.
Warm the pan. Set a 10-inch (25 cm) nonstick skillet over medium-low heat and add the oil. Tilt the pan to coat its base. Give it about 1–2 minutes to warm; the oil should look loose and shiny, not smoke. A pan that is too hot can brown the underside before the egg mixture has time to set in the middle. Reduce the heat if the oil begins to smoke.
Cook the omelette gently. Pour in the egg mixture and tilt the skillet so it spreads into an even layer. Cover with a lid and cook for about 6–8 minutes, checking the edges after the first 5 minutes. The edges should look set and the center should be mostly firm, with no large pool of raw egg. If the top is still wet, keep the pan covered and cook in 1-minute increments over low heat. A thin spatula can help you lift an edge to check whether the bottom is golden rather than deeply browned.
Check doneness and finish. Before folding, check the thickest part of the omelette with a food thermometer. USDA FSIS guidance sets the safe minimum internal temperature for egg dishes at 160°F (71°C); if it has not reached that temperature, cover the pan and cook for another minute, then check again. When cooked through, fold the omelette in half with a spatula, or slide it onto a plate and fold it there. Scatter over the reserved scallions and serve while warm.

Tips

Choose the right flour. Use ordinary rice flour, sometimes labeled white rice flour. Glutinous or sweet rice flour behaves differently and can make the mixture gummy. If rice flour is unavailable, substitute 1 tablespoon (8 g) cornstarch; it will help bind the eggs, but the omelette will not have the same delicate, slightly springy texture.
Whisk out every lump. Mixing the flour with water before adding the eggs is more reliable than sprinkling dry flour directly into beaten eggs. If small lumps remain, press them against the side of the bowl with a whisk or fork. The batter should be pourable, not doughy.
Keep the heat moderate. Rice flour can brown quickly where it touches the pan, and high heat can leave the center undercooked. Use a nonstick skillet, a thin coating of oil, and a lid. If you do not have a lid, cover the skillet loosely with foil, taking care to keep it away from the burner.
Adjust the fish sauce carefully. Fish sauces vary in saltiness, so start with the stated amount rather than adding extra by instinct. If you are using a particularly salty fish sauce, use 1½ teaspoons (7.5 ml) and taste a small cooked piece before deciding whether more seasoning is needed. The fresh herbs and lime at the table help balance the savory flavor.

Serving Suggestions

Serve the omelette hot or warm, cut into wedges, with cucumber slices, lime wedges, and a handful of fresh herbs. Cilantro and mint give a bright, familiar herbal contrast; Thai basil adds a more pronounced anise-like note. A bowl of steamed jasmine rice makes the dish a more filling meal, while a smaller wedge works well alongside rice, sautéed greens, or a simple vegetable soup.

For a dipping sauce, put a little fish sauce in a small dish and add lime juice and sliced chili to taste. Keep the sauce on the side rather than pouring it over the whole omelette, so the crisp edges remain intact. If serving several people, cut the omelette into bite-size pieces and arrange the herbs and cucumber nearby for guests to add as they eat. The dish is flavorful enough to stand on its own, so no elaborate garnish is needed.

Variations

Add vegetables: Fold ¼ cup (about 25 g) finely chopped cilantro or a small handful of thinly sliced onion into the eggs. For a vegetable with higher water content, such as mushrooms, cook it separately until its moisture has evaporated, let it cool briefly, and then add it to the egg mixture. Wet vegetables can release liquid as the omelette cooks and make the center soft.

Make it heartier: Stir in ¼ cup (about 35 g) cooked, finely chopped shrimp or cooked ground pork. Any meat or seafood must already be fully cooked before it goes into the egg mixture; the omelette’s cooking time is designed to set the eggs, not cook a raw filling safely. Keep the filling amount modest so the omelette can fold without breaking.

Change the seasoning: Add a small pinch of sugar (about 1 g) for a rounder, slightly sweet-savory flavor, or add sliced fresh chili for heat. For a vegetarian version, replace the fish sauce with 2 teaspoons (10 ml) light soy sauce. That swap changes the flavor and color, so the omelette will taste less distinctly fish-sauce-seasoned; check the soy sauce label if you need to avoid fish or other allergens.

Cook individual portions: Divide the mixture between two smaller skillets, or cook it in two batches in one pan. Smaller omelettes are easier to turn or fold, but they cook faster, so begin checking the centers after about 4 minutes. Keep the first portion warm on a plate while the second cooks, rather than leaving it in the hot skillet where it may overcook.

Storage and Reheating

For the best texture, serve the omelette soon after cooking. If you have leftovers, refrigerate them within 2 hours in a shallow, airtight container. They keep for 3–4 days in the refrigerator. Store the cucumber, herbs, and lime separately so they stay fresh, and do not leave the cooked eggs at room temperature while serving for longer than 2 hours.

Reheat a portion in a covered skillet over low heat with a teaspoon of water beside the omelette to create a little steam, or microwave it in short intervals until hot throughout. USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center with a food thermometer. The omelette may soften after chilling and reheating, so add fresh herbs and lime afterward for a brighter finish. Freezing is not ideal because thawed egg can turn watery or rubbery.

Frequently Asked Questions

Is rice flour traditionally used in every Vietnamese omelette?
No. Vietnamese trứng chiên has many home and regional versions, and rice flour is not required in all of them. This recipe uses a small amount to give the egg a tender, slightly springy body and help it hold together. You can leave it out, though the result will be closer to a straightforward seasoned egg omelette and may be a little softer.

Can I use glutinous rice flour instead?
It is better to use plain rice flour. Glutinous rice flour has different starch behavior and can make the omelette unusually sticky or chewy. If plain rice flour is unavailable, cornstarch is a more predictable substitute, although it will not give quite the same texture. Avoid adding extra flour to compensate for a thin-looking egg mixture; the batter is meant to remain pourable.

Can I make the mixture ahead?
For the best result, mix and cook it just before serving. If you need to prep ahead, whisk the rice flour and water together and chop the aromatics, then refrigerate those separately in covered containers. Beat the eggs and combine everything shortly before cooking. Keeping the egg mixture overnight can make the texture less even and leaves raw eggs sitting longer than necessary.

How do I stop the omelette from sticking or breaking?
Use a sound nonstick pan, preheat it gently, and coat the base with oil before pouring in the eggs. Let the edges set before attempting to fold; forcing a spatula underneath too early can tear the soft center. If folding feels risky, leave the omelette flat and slide it onto a plate. It will still taste the same and can be cut into wedges at the table.

How can I tell when the center is cooked?
The top should no longer look runny, and the omelette should feel set when you gently press the center with a spatula. For the food-safety check, use a thermometer in the thickest part and cook egg dishes to 160°F (71°C), the USDA FSIS safe minimum. Because thin omelettes can be awkward to probe, insert the thermometer from the side into the center rather than touching the pan.

Can I make this without fish sauce?
Yes. Use the same amount of light soy sauce for a savory alternative, or use a vegetarian fish-sauce substitute if you have one. The flavor will change: soy sauce is less briny and usually gives the eggs a slightly darker color. If you omit both, season with a small pinch of salt and serve lime or a dipping sauce at the table so the finished omelette still has a lively, balanced taste.
