Few foods are as disappointing to reheat as egg rolls done poorly. When microwaved, they turn limp and chewy. When overheated, they dry out and harden. But when reheated correctly in the oven, frozen egg rolls can come out with a crisp, blistered shell and a steamy, flavorful interior that tastes freshly fried.
The oven works so well because it reheats the filling evenly while restoring crunch to the wrapper – something other methods struggle to balance. The key is using the right temperature, timing, and technique.
Let’s break it down step by step.

This range hits the sweet spot:
Temperatures below 350°F tend to dry the egg roll out before it crisps, leading to a tough, leathery shell.
Above 425°F, the outside can brown too quickly while the inside remains cold, especially if the egg rolls are still fully frozen.
If your oven runs hot, stick closer to 375°F. If it runs cool, 400°F is usually safe.
Cooking time depends on size and thickness, but here are reliable guidelines:
| Egg Roll Size | Temperature | Time (From Frozen) |
|---|---|---|
| Small | 400°F | 12-15 minutes |
| Medium | 400°F | 15-18 minutes |
| Large | 400°F | 18-22 minutes |
Flip halfway through cooking for even browning.
You’ll know they’re ready when:
Follow this method for the best texture:
Preheat to 400°F. Starting with a fully hot oven is crucial for crisping.
Use one of these setups:
Best option: A wire rack on top of a baking sheet
This allows air to circulate underneath, crisping all sides.
Place them in a single layer with space between each one. Overcrowding traps steam and causes sogginess.
A light mist of cooking spray helps restore a fried-like crunch. Don’t drench them – just a quick pass.
Bake for half the total time, flip each roll, then finish baking.
Let them sit for 2-3 minutes before eating. This allows the filling to settle and avoids mouth burns.
Sometimes reheating isn’t worth the risk or the result.
Do not reheat if:
Freezer burn alone doesn’t make egg rolls unsafe, but it can cause dry texture and dull flavor.
Reheating more than once is not recommended.
Each cooling and reheating cycle gives bacteria more opportunity to grow, especially if the food spends time in the temperature ’danger zone’ (40°F-140°F).
For best safety and quality:
You can adjust, but you’ll need to modify cooking time.
| Temperature | What Happens | Time Adjustment |
|---|---|---|
| 350°F | Less crisp, slower heating | Add 5-8 minutes |
| 375°F | Slightly gentler crisping | Add 2-4 minutes |
| 425°F | Faster browning, burn risk | Reduce by 3-5 minutes and watch closely |
Higher heat = shorter time but more risk of over-browning.
If you cook for less time, the outside may look done while the center is still cold. Always check:
If you cook for too long, expect:
If this happens, serve with sauce to add moisture.
While the oven is the most balanced method, here are comparisons:
Crispy outside, evenly heated inside.
375°F for 8-12 minutes. Excellent crunch, slightly drier interior.
Microwave 30-45 seconds to warm the center, then bake 8-10 minutes to crisp. Good for thick rolls.
Fast but leaves the wrapper soft and chewy.
Yes, frozen egg rolls can be reheated directly in the oven without thawing. Preheat the oven to 375°F (190°C) and place the egg rolls on a baking sheet lined with parchment paper. Bake for 20-25 minutes, turning halfway through, until the exterior is crispy and the internal temperature reaches at least 165°F (74°C).
It is not necessary to cover frozen egg rolls with foil. Leaving them uncovered allows the exterior to crisp up properly. Covering them may result in a softer, less crunchy texture.
To prevent dryness, lightly brush or spray the egg rolls with oil before baking. This helps retain moisture inside while ensuring the exterior becomes golden and crispy.
The ideal temperature is 375°F (190°C). This allows the egg rolls to heat evenly and achieve a crispy texture without burning the exterior before the inside is fully warmed.
Reheating frozen egg rolls in a conventional oven typically takes 20-25 minutes at 375°F (190°C). Flip them halfway through the baking time to ensure even crisping on all sides.
Yes, a convection oven can be used. Reduce the temperature to 350°F (175°C) and bake for 15-20 minutes, turning halfway through. The circulating air helps achieve even crispiness faster.
Egg rolls are fully reheated when the exterior is golden and crispy and the internal temperature reaches at least 165°F (74°C). You can check the center with a food thermometer or cut one open carefully to ensure it is steaming hot throughout.
Yes, preheating the oven ensures even cooking. Placing frozen egg rolls in a fully preheated oven helps the exterior crisp up quickly while the interior heats evenly.
Yes, you can reheat multiple egg rolls at once. Arrange them in a single layer on the baking sheet without overlapping. Overcrowding may lead to uneven heating and less crispy exteriors.
Yes, placing egg rolls on a wire baking rack over a sheet pan allows air to circulate around them, resulting in a uniformly crispy exterior. This method is especially useful when reheating larger batches.
