How to reheat tamales for a crowd without a steamer

You need to reheat tamales for a crowd, you do not own a steamer, and the guests arrive in two hours. I have taken that phone call more times than I can count, usually from someone standing in a kitchen with five dozen cold tamales and one small pot. Relax. The oven does this job beautifully, and so do a few other things you probably already own.

The short answer: Lay the tamales in a deep pan in their husks, no more than two layers deep, splash in a quarter cup of water per dozen, cover tightly with foil, and bake at 325°F for 25–35 minutes from the fridge or 40–50 minutes from frozen. One full-size pan holds about two dozen, so five dozen means three pans and one oven cycle.

Why a crowd changes the math

Reheating one tamal is easy. Reheating sixty is a different problem, and the difference is not the food, it is the heat. A single tamal in a steamer basket is surrounded by steam on every side. Sixty tamales packed into a pot become one big cold block, and the ones in the middle stay cold long after the ones on the outside are hot. That is how people end up serving tamales that are lukewarm in the center and mushy at the edges.

The fix is to spread them out. A wide, shallow pan gives every tamal a share of the heat. Two layers is the limit I hold myself to. Three layers works in theory, but the middle layer always lags, and you will end up opening the foil every ten minutes to check, which lets the steam out and slows everything down further.

The second thing a crowd changes is timing. Whatever method you choose, plan for the tamales to be ready 20 minutes before you want to serve. Hot tamales in a covered pan hold well. Cold tamales with hungry people standing around do not.

The covered oven method for two to ten dozen

This is what I recommend to everyone who does not have a tamalera, and honestly, when I am feeding my own family, it is what I use too. The oven does not need babysitting and it can hold three pans at once.

1. Heat the oven to 325°F. Hotter does not help. It dries the outside before the middle is warm.
2. Take a deep pan, either a 9×13 baking dish or a full-size disposable aluminum pan. Lay the tamales flat, husks on, in one or two layers. Leave them in the husk; it is the built-in wrapper that keeps the masa moist.
3. Add a quarter cup of water per dozen. Pour it into the corners, not over the tamales. This is the whole trick: the water turns to steam inside the covered pan and does what a steamer would have done.
4. Cover with heavy-duty foil and crimp every edge. If the foil is thin, use two sheets. A loose seal is the number one reason people call me to say the oven method did not work.
5. Bake 25–35 minutes for refrigerated tamales. A single layer needs the short end, two layers need the long end.
6. Check one from the middle of the pan. Open the husk; the masa should pull away cleanly and steam in the center. If it does not, re-cover and give it ten more minutes.

Our tamales are big, the kind reviewers describe as packed with meat, so if you ordered from us, lean toward the longer time. A skinny store tamal can be done in 20 minutes; ours want the full 35 when the pan is stacked.

Two pans side by side on one rack heat about the same as one. Three pans on two racks need you to swap the racks halfway through, because the top of most home ovens runs hotter than the bottom.

Slow cooker, roaster and chafing dish: the other no-steamer options

The oven is my first choice, but it is not the only one. Each of these works, with one caveat each.

Slow cooker

Pour a half cup of water in the bottom, stand the tamales upright with the open ends up, and set it to high. A large oval cooker holds about a dozen and a half. They will be hot in 60–90 minutes, and then the cooker turns into a warmer for the rest of the party. The caveat: it is slow, so start early, and a full cooker takes longer than a half-full one.

Electric roaster

An 18-quart roaster is the closest thing to a steamer most households own. A cup of water in the bottom, tamales stacked no more than two deep on the rack, lid on, 325°F, and you can bring four dozen back in about 40 minutes. The caveat: check the water once, because a roaster that boils dry scorches the bottom layer.

Chafing dish

Two chafing fuel cans under a water pan will not reheat cold tamales in any reasonable time, but they will hold hot tamales for two hours. Reheat in the oven, then move the tamales to the chafer to serve. That is exactly how I set up buffet service for backyard parties and family gatherings when the food has to sit while people arrive.

Microwave, for a few at a time

It will not do a crowd, but if the oven is full of something else, a microwave will finish a few stragglers: husk on, damp paper towel, one minute, flip, then 30-second bursts. Never more than four at a time or the middle ones stay cold.

Reheating frozen tamales for a crowd

Frozen tamales are the reason a lot of people search for this. They ordered ahead for a holiday, froze them, and now the day is here. Good news: frozen tamales reheat in the oven from solid, no thawing needed, and they often come out better than thawed ones because the ice inside turns into steam.

Use the same method, with two changes. Add a bit more water, about a third of a cup per dozen, and add 15–20 minutes to the time. Do not stack frozen tamales two deep unless you have to; they thaw unevenly and the bottom layer sits in meltwater. If you froze them in a block, run the bag under cold water for a minute so you can pry them apart before they go in the pan.

If you have the time, the best result comes from moving the tamales from the freezer to the fridge the night before. Then they reheat like fresh ones, on the shorter schedule. My notes on freezing and storing tamales cover how to wrap them so they come out of the freezer without freezer burn in the first place.

Keeping them hot once they are ready

A tamal has a built-in advantage here. The husk and the dense masa hold heat the way a baked potato does, so a covered pan of hot tamales stays serving temperature for a good 45 minutes on a counter, and longer with a towel draped over the foil. In the oven at its lowest setting, still covered, they hold for an hour and a half without drying out.

What ruins them is uncovering. Every time the foil comes off, steam escapes and the tops start to firm up. Keep the pan sealed until the moment of serving, then take the foil off one pan at a time. I explain the longer holding tricks, including the cooler method that works for outdoor events, in my guide to keeping catered food hot for hours.

Salsa should be room temperature or gently warmed, never cold from the fridge, because a cold spoonful of salsa on a hot tamal cools it instantly. Warm the red or green salsa in a small pot on low while the oven works.

Mistakes I see at every party

• Peeling the husks before reheating. Unwrapped masa dries out in the oven. Reheat in the husk, then let guests unwrap their own; it is part of the fun.
• Skipping the water. A dry covered pan is just a slow oven. The water is what makes the steam.
• Loose foil. If you can see steam leaking, you are losing moisture and time. Crimp it like you mean it.
• Cranking the oven to 400°F to hurry. The outsides toughen, the middles stay cold, and you have lost nothing but quality.
• Stacking three or four deep. Use another pan. Disposable pans cost less than a ruined dozen.
• Reheating twice. Reheat only what you will serve. Leftovers go back in the fridge and get reheated once, later, not warmed and cooled and warmed again.

For the small-batch versions of all of this, steamer, air fryer and skillet included, see my main guide on how to reheat tamales so they taste fresh. The principles are the same; only the pan size changes.

Or skip the reheating altogether

Here is the honest alternative. When you order tamales by the dozen from Maggie’s for a party, our own team delivers them hot, in an agreed window, labeled pork or chicken, with salsas and serving spoons if you want buffet service. Nobody in your house touches an oven. That is true for a birthday for 30, a church lunch for 100, and every holiday pre-order in December. Tell me the date and the headcount and I will price it the same business day. Request a catering quote and let the reheating be my problem.

Frequently asked questions

How do you reheat tamales for a crowd without a steamer?

Use the oven. Lay the tamales in their husks in a deep pan, one or two layers, add a quarter cup of water per dozen, seal the pan tightly with foil, and bake at 325°F for 25–35 minutes from the fridge. The water becomes steam inside the pan and does the steamer’s job. A full-size pan holds about two dozen, and three pans fit in most ovens at once.

How long does it take to reheat 5 dozen tamales in the oven?

About 35 minutes at 325°F if they are refrigerated and spread across three covered pans no more than two layers deep. From frozen, plan on 50–55 minutes. Check a tamal from the center of the middle pan before you serve; if the masa is not steaming in the middle, re-cover and give it another ten minutes. Start 20 minutes earlier than you think you need to.

Can I reheat tamales in a slow cooker for a party?

Yes, but it is slow. Pour a half cup of water in the bottom, stand the tamales upright with open ends up, and run it on high for 60–90 minutes. A large slow cooker holds about a dozen and a half. Once the tamales are hot, switch to the warm setting and the cooker becomes a holding station for the rest of the party.

Do I need to thaw frozen tamales before reheating them for a crowd?

No. Frozen tamales go straight into a covered pan with a third of a cup of water per dozen and bake at 325°F for 40–55 minutes depending on how many are in the pan. Keep frozen tamales to a single layer where you can. If you have time, thawing overnight in the fridge shortens the reheat to the normal 25–35 minutes and gives slightly more even results.

How do I keep reheated tamales warm for two hours?

Keep them covered. A sealed foil pan of hot tamales holds serving temperature for about 45 minutes on the counter, an hour and a half in a low oven, and two hours or more in a chafing dish over a water pan. The husk and the dense masa hold heat well. What dries them out is uncovering the pan repeatedly, so take the foil off one pan at a time.

Can Maggie’s deliver the tamales already hot so I skip all of this?

Yes, and for anything over a couple of dozen that is what I recommend. Catering orders are delivered hot by our own team in an agreed window, labeled by filling, with salsas, crema and serving spoons on request. Use the quote form or call the kitchen with your date and headcount and I will send a menu and a price, usually the same business day.
