How to Microwave Lentils (Red, Green, and Brown)

Can You Really Cook Lentils in the Microwave?

Lentils have a reputation for being fussy — soak them, simmer them, babysit the pot. I get why people avoid them on a weeknight.

The short answer is yes — you can cook lentils entirely in the microwave, red lentils in about 10 minutes and green or brown lentils in 15 to 20.

I’ve made lentils this way more times than I can count when I didn’t want to dirty a saucepan or stand over the stove.

It works because lentils just need water, heat, and time — the microwave supplies all three, it just does it in short, controllable bursts instead of one long simmer.

They’re also worth the small effort: lentils pack in more protein and fiber than most rice or pasta, according to USDA FoodData Central’s entry for raw lentils.

If you’re building a legume-heavy meal, it’s also worth comparing notes with our guide on how to microwave baked beans, since the bowl-and-cover logic is nearly identical.

What Kind of Lentils Are You Cooking?

Before you set a timer, figure out which lentils are in your pantry — it changes everything about how you microwave them.

Red and yellow lentils are split and hulled, so they’re thinner and cook fast — they’re the ones people mean when they ask about microwave red lentils.

Brown and green lentils keep their skins, so they hold their shape longer and take more time and, ideally, a soak.

French green lentils, sometimes labeled Puy lentils, are the firmest of the bunch and hold together best in salads.

One thing that trips people up: recipes labeled simply ‘lentils’ at the grocery store are almost always brown lentils unless the bag says otherwise.

How to Microwave Red Lentils (No Soaking Required)

This is the one I reach for on busy nights, since red lentils genuinely don’t need a soak.

Rinse 1 cup of red lentils in a fine-mesh strainer until the water runs mostly clear — this removes surface starch that can make them foam over.

Yes, you can microwave rinsed lentils straight away; there’s no waiting period required for split red or yellow lentils.

Put the rinsed lentils in a large microwave-safe bowl and cover with about 3 cups of water — you want at least 2 inches of water above the lentils, since they expand fast.

Microwave uncovered on high for 5 minutes, stir, then continue in 2-minute bursts, checking each time, until they’re soft and starting to break down — usually 8 to 10 minutes total.

In my experience, red lentils go from firm to mush in about 90 seconds flat, so this is exactly where you want to slow down and check often rather than walking away.

This is also the fastest route if you’re making red lentil soup or dal, since red lentils naturally soften into a thick, spoonable texture as they cook.

How to Microwave Green or Brown Lentils (With a Soak)

Whole green and brown lentils are tougher, so a soak genuinely helps here — this is the step people skip and then wonder why the middle stays chalky.

Rinse 1 cup of lentils, cover generously with cold water, and let them sit for at least 2 hours, or overnight in the refrigerator if you’re planning ahead.

Drain the soaking water and refill with fresh water, covering the lentils by about an inch.

Microwave, uncovered, on high for 7 minutes, then drain and add fresh water again — this two-stage approach helps them cook more evenly than one long blast.

Microwave a second time for 7 to 10 minutes, checking with a fork around the 7-minute mark; you’re looking for lentils that give with gentle pressure but aren’t falling apart.

If your microwave runs on the weaker side, add time in 2-minute increments rather than guessing at one long cook — a 700-watt microwave can need several extra minutes compared to a 1,200-watt one.

Do You Have to Soak Green and Brown Lentils?

Not strictly — you can skip the soak and just add 5 to 8 extra minutes of microwave time.

But in my experience, unsoaked whole lentils cook less evenly, with soft outsides and a firmer center, especially in a lower-wattage microwave.

Cooking Lentils in the Microwave With an Anyday-Style Dish

If you’ve seen the trend of cooking entire meals in a covered glass dish — the kind sold under the Anyday brand — lentils are actually a great candidate for it.

These dishes are designed with a vented glass lid that traps steam without letting pressure build, which suits lentils well since they release a lot of starchy foam.

The method doesn’t really change: rinse your lentils, add water to the fill line the dish suggests, cover with the vented lid, and microwave in the same stages described above.

The main advantage is less mess — you’re not repeatedly pulling plastic wrap on and off, and the lid keeps splatter contained if the water starts to bubble up.

A regular microwave-safe glass bowl with a loose-fitting lid or a plate on top works almost as well if you don’t own one of these specific dishes.

How to Keep Microwave Lentils From Turning Mushy

This is the question I get asked most, and it usually comes down to timing, not technique.

The trick I always come back to is pulling lentils off the heat slightly before they look fully done — residual heat keeps cooking them for another minute or two after the microwave stops.

Stir gently rather than vigorously; aggressive stirring breaks the lentils apart and speeds up that mushy slide, especially with red lentils.

Use just enough water — too much extra water means lentils simmer longer than they need to just to reduce it down.

Start checking earlier than you think you should; at the 6-minute mark for red lentils and the 12-minute mark for green or brown, rather than waiting for your first guess at total time.

If you want firmer lentils for a salad, undercook them very slightly, drain immediately, and spread them on a plate to stop the cooking fast.

Flavor Variations: Moroccan-Style Microwave Lentils

Once you’ve got the basic method down, Moroccan-style lentils are one of my favorite ways to dress them up without extra pans.

Use red or brown lentils, and during the second cooking stage, stir in a diced tomato, a clove of minced garlic, a teaspoon of cumin, a pinch of cinnamon, and a small splash of olive oil.

Microwave as usual, checking at the same intervals, then finish with a squeeze of lemon and chopped cilantro once the lentils are tender.

If you’re prepping the tomatoes ahead, our guide on how to microwave tomatoes is a quick way to soften them before stirring them in.

This spiced version holds up well as a side for roasted vegetables or spooned over rice.

What About Red Lentil Wraps in the Microwave?

If you’ve searched for red lentil wraps in the microwave, it’s worth clarifying what you’re actually cooking.

Store-bought red lentil wraps are already fully cooked flatbreads made from lentil flour — you’re reheating them, not cooking raw lentils into a wrap.

Wrap one in a damp paper towel and microwave on high for 15 to 20 seconds to soften it without drying out the edges.

If you’re stacking several, layer them with paper towels between each one and add 5 to 10 seconds per extra wrap.

For a similar quick-reheat approach with a different wrapped food, our piece on how to microwave bao buns covers the same damp-towel trick in more detail.

Don’t try to microwave raw lentil batter into a wrap shape — without a hot, dry pan surface, it won’t set properly and will stay gummy in the middle.

Is It Safe to Microwave Dried Lentils?

This is a genuinely important question, and it deserves a straight answer rather than a quick reassurance.

Dried lentils don’t carry the same phytohaemagglutinin toxin risk that raw or undercooked red kidney beans do, a hazard the FDA’s Bad Bug Book entry on phytohaemagglutinin describes in detail for kidney beans specifically.

That said, microwaving dried lentils doesn’t automatically make them safe or digestible — they still need enough water and enough time at a full simmer-equivalent heat to soften all the way through.

Lentils that are undercooked can be genuinely hard to digest and may cause more gas or bloating than properly cooked ones, which is one reason fiber-rich legumes are best eaten fully softened, per general guidance from MedlinePlus’s page on dietary fiber.

Never microwave lentils completely dry with no water — without enough liquid, they can scorch, smoke, or even char inside the microwave.

If you have a digestive condition or are otherwise advised to limit high-fiber foods, it’s worth checking with a healthcare professional about how much lentil fiber is appropriate for you, since fiber needs vary a lot person to person, as noted by Mayo Clinic’s guidance on high-fiber foods.

Serving Ideas for Microwave Lentils

Once your lentils are tender, they’re a blank canvas — I usually build a whole bowl around whatever’s already in the fridge.

Stir cooked lentils into a quick grain bowl with roasted vegetables, or fold them into a soup base for extra body.

For a fast veggie side to go with them, our guide on how to microwave frozen peas takes about the same amount of time as the last stretch of cooking your lentils.

They also work surprisingly well stirred into a cheesy dish — if you’re feeding kids alongside the adults, how to microwave mac and cheese is an easy second dish to run at the same time.

Leftover cooked lentils keep in the fridge for about 4 to 5 days in a sealed container, and they reheat well in the microwave with a splash of water to loosen them back up.
