How to Reheat Rice in Oven

Reheating rice safely and without it becoming dry and clumped is easier than most people think — the oven method is particularly good for large quantities or rice dishes like pilaf, fried rice, or rice bakes. Here's how to do it correctly and safely.

Food Safety: The Most Important Rule for Reheating Rice

Rice can contain Bacillus cereus spores that survive cooking and can multiply rapidly if rice is left at room temperature. Always:

• Cool cooked rice quickly and refrigerate within 1 hour of cooking
• Store in the fridge for no more than 1 day
• Reheat only once — never reheat rice more than once
• Ensure rice is steaming hot throughout (75°C / 165°F) before serving

How to Reheat Rice in the Oven: Step by Step

1. Preheat the oven to 160–170°C (320–340°F)
2. Place rice in an oven-safe dish — spread it out rather than piling it deep for more even heating
3. Add water: Sprinkle 2 tablespoons of water per cup of rice over the surface. This is essential — rice dries out significantly in the fridge and needs moisture to steam back to fluffy.
4. Break up any clumps with a fork before covering
5. Cover tightly with foil — the trapped steam rehydrates the rice as it heats
6. Reheat for 15–20 minutes until steaming hot throughout
7. Fluff with a fork before serving

Reheating Rice Dishes in the Oven

Pilaf and Seasoned Rice

• Add a splash of stock instead of water for extra flavour
• Cover and reheat at 160°C (320°F) for 15–20 minutes

Rice Bake / Arroz al Horno

• Add extra sauce or stock if the dish looks dry
• Cover and reheat at 170°C (340°F) for 20–25 minutes
• Remove foil for the last 5 minutes to re-crisp the top

Fried Rice

• Add a splash of water and a drizzle of soy sauce
• Cover and reheat at 160°C (320°F) for 15 minutes
• Stir halfway through for even heating

Use the Right Dish

A ceramic or porcelain baking dish with a lid (or covered with foil) is ideal for reheating rice. The MALACASA Porcelain Baking Dishes Set of 4 (9.4"/11.1"/12.2"/14.7") are oven-safe and come in multiple sizes — perfect for reheating everything from a single portion to a large batch of rice.

Easy Covering with Foil

The Pre-Cut Aluminum Foil Sheets (200 Count, 12x10.6 inch) make covering dishes quick and easy — lay a sheet over the dish and crimp the edges for a tight steam seal that keeps moisture in the rice throughout reheating.

How to Tell When Rice Is Properly Reheated

• Rice is steaming visibly when uncovered
• Grains are separate and fluffy, not clumped
• The centre of the dish is hot to the touch — insert a knife and hold for 5 seconds
• Internal temperature reaches 75°C (165°F)

Oven vs. Microwave for Reheating Rice

• Oven: Better for large quantities and rice dishes — more even heating, better texture for pilaf and rice bakes
• Microwave: Faster for single portions — add water, cover, and microwave on medium power in 1-minute bursts, stirring between each

Summary

Reheat rice in the oven at 160–170°C (320–340°F) with 2 tablespoons of water per cup of rice, covered tightly with foil, for 15–20 minutes. Always ensure rice is steaming hot throughout before serving, and never reheat rice more than once.
