Your cravings are screaming for something deeply comforting, but your energy is whispering, “please, not another complicated project.” I hear you. I live that reality more often than I’d like to admit!

That’s exactly why this recipe for Lentil Stew Over Creamy Mashed Potatoes is my forever favorite. It’s the hero of my weeknight dinner rotation, the dish I make for potlucks that has everyone asking for the recipe, and the ultimate proof that “comfort food” doesn’t have to mean “heavy and boring.” We’re taking humble, beautiful ingredients and turning them into a symphony of flavor and texture.

So, tie on your favorite apron, put on some good music, and let’s make a meal that’s guaranteed to bring all the good vibes to your table.

A Pot of Stew and a Full Table

This recipe takes me right back to my grandma’s kitchen in our little coastal town. Sundays were for big, noisy family dinners, and without fail, if you walked in the door, you’d be greeted by the most incredible aroma—a pot of something hearty bubbling away on the stove. While my grandma was famous for her fish chowder, my version of that “welcome home” feeling is this lentil stew.

I remember one particularly blustery autumn evening. I’d just moved into my first apartment, and a bunch of my friends, all equally broke and tired from work, came over. The cupboards were… creative. But I had lentils, some sad-looking carrots, onions, and potatoes. I made a giant pot of this stew, doubling the recipe just like we’re doing here. We piled onto the floor around my coffee table, bowls steaming, and the room went quiet except for the sound of happy eating. It was one of those pure, simple moments of connection. That’s the magic of food like this. It’s not about fancy ingredients; it’s about filling bellies and warming hearts. Every time I make this dish, I feel a little of that Sunday night magic all over again.

Gathering Your Flavor Party

Here’s everything you’ll need to create this double-batch of deliciousness. Don’t be intimidated by the list—it’s mostly pantry staples! I’ve included my favorite tips and swaps to make this recipe work for you.

For the Lentil Stew:

• 2 cups dry green or brown lentils, rinsed – These are the heart of the stew! I love green or brown lentils because they hold their shape beautifully and have a lovely, earthy flavor. Chef Insight: Don’t use red lentils for this! They turn to mush, which is great for dahl, but we want some texture here.
• 2 tbsp olive oil – Our cooking fat of choice for building flavor from the start.
• 2 onions, diced – The flavor foundation. Yellow or white onions are perfect.
• 4 carrots, sliced – For a touch of natural sweetness and gorgeous color.
• 4 celery stalks, sliced – This is our secret weapon for a deep, savory base (this trio of onion, carrot, and celery is called a mirepoix, fancy, right?).
• 6 garlic cloves, minced – Because more garlic is always the answer. Always.
• 2 cans (14.5 oz each) diced tomatoes – They bring a bright acidity and body to the broth. Fire-roasted diced tomatoes are a fantastic upgrade for a smoky hint!
• 8 cups vegetable broth – This is the liquid gold that everything simmers in. Use a good-quality broth for the best flavor. Substitution Tip: Chicken broth works great if you’re not vegetarian.
• 2 tsp dried thyme – Herby, slightly floral, and classic for stews. If you have fresh thyme, use 2 tablespoons of the leaves.
• 1 tsp smoked paprika (our optional twist!) – This is my not-so-secret weapon. It adds a warm, smoky depth that makes the stew taste incredibly complex. Don’t skip it if you have it!
• 2 bay leaves – They infuse the broth with a subtle, woodsy flavor. Just remember to fish them out before serving!
• 1 tbsp balsamic vinegar (our second optional twist!) – A splash at the end brightens everything up and adds a rich, tangy sweetness. It’s a total game-changer.
• Salt and pepper to taste – Season in layers! We’ll add some as we go.

For the Creamy Mashed Potatoes:

• 8 large potatoes, peeled and chopped – Russet or Yukon Gold potatoes are my top picks. Russets are fluffy, Yukons are naturally buttery and creamy. You can’t lose! Chef Hack: You can leave the skins on Yukon Golds for a more rustic mash with extra fiber.
• 1 cup milk (or plant-based alternative) – For creaminess. Warm it up a bit before adding to the potatoes for a smoother texture.
• 8 tbsp butter (or vegan butter) – Because buttery potatoes are happy potatoes. Salted butter is fine, just adjust your added salt.
• 4 garlic cloves, roasted (optional twist!) – If you have an extra 20 minutes, roasting garlic transforms it into a sweet, mellow, spreadable paste that makes these mashed potatoes legendary.
• Salt and pepper to taste – Potatoes need a good amount of salt. Taste and season!

Let’s Get Cooking: Building Layers of Flavor

Okay, now for the fun part! We’ll multitask a little here to get dinner on the table efficiently. I like to get the potatoes boiling first, then start the stew. They’ll be ready around the same time!

1. Start the Mashed Potatoes.Place your peeled and chopped potatoes in a large pot and cover them with cold, salted water. Bring it to a boil over high heat, then reduce to a simmer. Cook for 15-20 minutes, or until the potatoes are fork-tender. Chef Tip: Starting with cold water ensures the potatoes cook evenly all the way through!

   While the potatoes are boiling, you can roast the garlic for the ultimate flavor boost if you’re using it. Just wrap the whole garlic cloves (skin on) in a little foil pouch with a drizzle of olive oil and pop them in a 400°F (200°C) oven for about 20 minutes. They’ll be soft, golden, and smell amazing.

2. Drain and Mash.Once the potatoes are tender, drain them well in a colander. Return them to the hot pot and let them sit for a minute off the heat so any residual water evaporates. This is the secret to non-watery mashed potatoes! Now, add the warm milk, butter, and the soft, roasted garlic (just squeeze it out of its skin). Mash everything with a potato masher or ricer until it’s smooth and creamy. Season generously with salt and pepper, cover, and set aside to keep warm.
3. Prepare the Stew Base (The Holy Trinity!).While the potatoes are cooking, grab your largest pot or Dutch oven. Heat the olive oil over medium heat. Add the diced onions, carrots, and celery. Sauté them for 8-10 minutes, stirring occasionally, until the onions are translucent and the carrots have softened a bit. Chef Insight: Don’t rush this step! Letting these veggies soften and sweeten is what builds a deep, flavorful foundation for your stew.
4. Add the Aromatics.Add the minced garlic, dried thyme, smoked paprika, and a good pinch of salt and pepper to the pot. Stir and cook for just one minute until the garlic is fragrant. Chef Warning: Don’t let the garlic burn! It only needs a minute to wake up its flavors.
5. Combine and Simmer.Now, add the rinsed lentils, the two cans of diced tomatoes (with their juices), the vegetable broth, and the bay leaves. Give it all a good stir. Bring the pot to a lively boil, then immediately reduce the heat to low so it’s at a gentle simmer. Let it cook uncovered for 35-40 minutes, stirring occasionally. You’ll know it’s done when the lentils are tender but not mushy.
6. The Final Flourish.Once the lentils are perfect, turn off the heat. Fish out and discard the bay leaves. Now, stir in that magical tablespoon of balsamic vinegar. Taste the stew! This is your moment. Does it need more salt? A crack of black pepper? Adjust the seasoning until it sings to you.

Plating Up Your Masterpiece

This is the best part! Grab your biggest, coziest bowls. Use a large spoon or an ice cream scoop to place a generous mound of creamy mashed potatoes right in the center. Then, ladle the hot, fragrant lentil stew all around and over the top of the potato mountain. I love to finish it with a fresh flourish—a sprinkle of chopped fresh parsley or chives, a crack of black pepper, or even a tiny drizzle of extra virgin olive oil. The contrast of the bright, savory stew with the creamy, rich potatoes is pure comfort food perfection. Serve it immediately while it’s piping hot!

Make It Your Own: Creative Twists

This recipe is a fantastic canvas for your own creativity! Here are a few of my favorite ways to mix it up:

• Spicy Kick: Add a pinch of red pepper flakes with the other dried spices, or stir in a tablespoon of harissa paste at the end.
• Greens for Goodness: Stir in a few handfuls of chopped kale or spinach during the last 5 minutes of the stew’s cooking time for a boost of color and nutrients.
• “Cheesy” & Vegan: For a dairy-free, cheesy flavor in the potatoes, add 2-3 tablespoons of nutritional yeast when mashing.
• Umami Bomb: Add a tablespoon of soy sauce or tamari to the stew along with the balsamic vinegar for an extra hit of savory depth.
• Herb Garden Delight: Stir a handful of fresh, chopped herbs like rosemary or oregano into the stew right before serving.

Isla’s Chef Notes

This recipe has evolved so much in my kitchen over the years. The first time I made it, it was just lentils, onions, and broth—simple survival food! The balsamic vinegar trick was a happy accident one day when I was trying to balance the acidity of the tomatoes, and it instantly became a non-negotiable step.

One of my favorite kitchen stories involves this stew. I was filming a quick video for Instagram and my cat, Pickles, decided it was the perfect moment to leap onto the counter right as I was pouring the stew over the potatoes. Let’s just say there was a very dramatic, slow-motion spill and a very un-chef-like squeal. The video never made it online, but the stew was still delicious (and Pickles got a tiny taste, don’t tell anyone). The moral of the story? Even when there’s a little chaos, the food still turns out great. Don’t stress the small stuff!

Your Questions, Answered!

I’ve gotten a lot of questions about this recipe over the years. Here are the most common ones to help you out!

Q: Can I make this ahead of time?
A: Absolutely! This is a fantastic make-ahead meal. Both the stew and the mashed potatoes can be made up to 3 days in advance. Store them separately in airtight containers in the fridge. Reheat the stew on the stove and the potatoes in the microwave (with a splash of extra milk to keep them creamy). You can also freeze the lentil stew for up to 3 months.

Q: My stew is too thin / too thick. How can I fix it?
A: No problem! Stews are very forgiving.
– Too Thin? Let it simmer uncovered for a bit longer to reduce and concentrate. You can also mash a small spoonful of the lentils against the side of the pot with a fork and stir it in—this will naturally thicken the broth.
– Too Thick? Simply stir in a little more vegetable broth or water until it reaches your desired consistency.

Q: I can’t find green or brown lentils. What can I use?
A: French Puy lentils are a great substitute as they also hold their shape. If you can only find red lentils, you can use them, but reduce the simmering time to about 15-20 minutes and expect a softer, more porridge-like texture. It will still taste delicious!

Q: My mashed potatoes are gluey! What did I do wrong?
A: The most common culprit is over-mixing! When you overwork potatoes, they release too much starch, which makes them gluey. Use a potato masher or ricer, and stop as soon as they are smooth. Avoid using a food processor or hand mixer if you can.
