The Story Behind the Stew: A Tale of Two Kitchens

This recipe has roots in two very different, but equally important, kitchens in my life. The first is my grandma’s kitchen, a place of warmth and wonderful chaos. She always had a pot of something bubbling away, and her mashed potatoes were legendary—fluffy, rich, and always served with a generous pat of butter melting right in the center. They were the ultimate comfort food.

The second kitchen was my first tiny apartment kitchen, where I was a broke but eager grad student learning to cook on a budget. Lentils became my hero—cheap, filling, and packed with protein. I’d whip up a big batch of lentil stew every Sunday, and it would see me through most of the week. One particularly exhausting, rainy Tuesday, I looked at my bowl of lentil stew and my container of leftover mashed potatoes from the night before and had a lightbulb moment. Why not put them together?

I piled the stew right on top of the potatoes, and friends, it was a revelation. The creamy potatoes mingled with the hearty, brothy stew, creating a texture and depth of flavor that was so much greater than the sum of its parts. It was the perfect marriage of my grandma’s timeless comfort and my own resourceful, flavor-loving spirit. It’s a combo I’ve been perfecting ever since.

Gathering Your Cozy Ingredients

One of the best things about this recipe is its flexibility. Don’t have a specific veggie? No problem! Want to add a little kick? Go for it! Here’s what you’ll need, along with my chef-y notes to guide you.

For the Hearty Lentil Stew:

• 2 cups dry lentils (green or brown), rinsed: These are the backbone of our stew! They hold their shape beautifully and have a lovely, earthy flavor. Chef’s Insight: Don’t skip the rinse! It washes away any dust and ensures your stew isn’t gritty.
• 2 tablespoons olive oil: Our cooking fat of choice for building flavor from the start.
• 2 onions, diced: The aromatic foundation. Yellow onions are perfect here for their balance of sweetness and sharpness.
• 4 carrots, sliced: They add a subtle sweetness and beautiful color. Substitution Tip: No carrots? Try parsnips or even a diced sweet potato!
• 4 celery stalks, sliced: The classic partner to onions and carrots, adding a necessary herbaceous note.
• 6 garlic cloves, minced: Because more garlic is always the answer. This is a no-judgment zone—feel free to add an extra clove or two!
• 2 cans (14.5 oz each) diced tomatoes: They bring a lovely acidity and body. Chef’s Insight: If you have them, fire-roasted diced tomatoes add a fantastic smoky depth.
• 8 cups vegetable broth: This is the soul of your stew’s liquid. Use a good-quality broth for the best flavor.
• 2 teaspoons dried thyme: Its woodsy flavor is a classic with lentils. Substitution Tip: Fresh thyme is wonderful too! Use about 2 tablespoons of fresh leaves.
• 2 bay leaves: They add a subtle, almost floral background note. Just remember to fish them out before serving!
• 1 tablespoon soy sauce (for umami depth): This is my secret weapon! It doesn’t make the stew taste like soy sauce; it just gives it a rich, savory, “something-special” quality. Substitution Tip: Tamari or coconut aminos work great for a gluten-free option.
• Salt and pepper to taste: Season in layers for the best result!
• Optional: ½ teaspoon smoked paprika or a pinch of chili flakes: For a hint of warmth and smoke. Highly recommended!

For the Cloud-Like Mashed Potatoes:

• 8 large potatoes, peeled and chopped: Russet or Yukon Gold potatoes are my top picks. Russets are fluffier, while Yukon Golds are naturally buttery and creamy. You can’t go wrong!
• 1 cup milk (or plant-based milk): This makes them creamy. Warm it up a bit before adding for the smoothest texture. Any milk you like works!
• 6 tablespoons butter (or vegan butter): The key to rich, decadent potatoes. Don’t be shy!
• Salt and pepper to taste: Potatoes need a good amount of salt. Taste as you go.
• Optional: 1 teaspoon garlic powder or a handful of chopped chives: For an extra flavor boost. Chives add a lovely fresh pop of color and flavor.

Let’s Get Cooking: Building Your Bowl of Comfort

Okay, now for the fun part! We’ll build the stew first, as it needs a little more time to simmer and develop its incredible flavor. You can get the potatoes going while the stew is bubbling away.

Step 1: Build Your Flavor Foundation (The Stew Base)

Grab your largest, heaviest-bottomed pot or Dutch oven and place it over medium heat. Add the olive oil. Once the oil shimmers, add your holy trinity of diced onions, sliced carrots, and sliced celery. We’re going to sweat these veggies, not sauté them. That means cooking them until they’re softened and sweet, but not browned, which should take about 7-8 minutes. Stir them occasionally and enjoy the incredible smell that starts to fill your kitchen! Chef’s Hack: Add a pinch of salt at this stage. It helps draw out the moisture from the vegetables, speeding up the softening process and building flavor from within.

Step 2: The Aromatic Punch

Once your veggies are tender, add the minced garlic. Cook for just one more minute, until it becomes fragrant. Be careful not to burn the garlic! Burnt garlic turns bitter, and we want all the sweet, aromatic goodness it has to offer.

Step 3: Bring in the Star and the Supporting Cast

Now, add the rinsed lentils, the two cans of diced tomatoes (with their juices!), the vegetable broth, dried thyme, bay leaves, soy sauce, and your optional smoked paprika or chili flakes. Give everything a big, hearty stir to combine.

Step 4: The Simmering Magic

Turn the heat up to high and bring the pot to a lively boil. Then, immediately reduce the heat to low, so the stew maintains a gentle simmer. Let it cook uncovered for 35-40 minutes. This uncovered simmer is key—it allows the liquid to reduce slightly, thickening the stew naturally and concentrating the flavors. The stew is ready when the lentils are tender but not mushy. Give it a taste and season generously with salt and black pepper. Chef’s Tip: The lentils will absorb a lot of the salt, so don’t be afraid to season well at the end.

Step 5: Create Your Cloud (The Mashed Potatoes)

While the stew is simmering, let’s make the potatoes. Place your peeled and chopped potatoes in a large pot and cover them with cold, generously salted water. Starting with cold water ensures the potatoes cook evenly from the outside in. Bring the water to a boil and cook for 15-20 minutes, or until the potatoes are fork-tender.

Drain the potatoes thoroughly in a colander. Then, return them to the hot pot and let them sit for a minute over the turned-off burner. This allows any residual steam to evaporate, which is the secret to non-watery mashed potatoes! Now, mash them to your desired consistency. I love using a potato ricer for the fluffiest results, but a good old-fashioned masher works perfectly.

Add the warm milk and butter, and continue mashing until smooth and creamy. Season with salt, pepper, and any optional add-ins like garlic powder or chives. Give it a final taste and adjust the seasoning. Cover to keep warm until the stew is ready.

Plating Up Your Masterpiece

This is my favorite part! Grab your coziest, biggest bowls. Spoon a generous, fluffy mound of mashed potatoes right into the center of each bowl. Then, ladle the hot, hearty lentil stew all around and over the potatoes. I love creating a little “volcano” effect. The stew will naturally pool around the creamy potatoes, creating a beautiful presentation. You can finish it with a fresh crack of black pepper or a sprinkle of fresh herbs like parsley or chives. Serve immediately and watch the happy faces around your table.

Make It Your Own: Delicious Twists & Swaps

The beauty of this dish is its adaptability! Here are a few ways to mix it up:

• Spicy Kick: Add a diced jalapeño or serrano pepper with the onions, or stir in a tablespoon of harissa paste with the tomatoes.
• Mediterranean Vibe: Swap the thyme for a teaspoon of dried oregano and a sprinkle of rosemary. Stir in a couple of handfuls of fresh spinach during the last 5 minutes of the stew’s cooking time.
• Creamy Dreamy: For an even richer stew, stir in a splash of heavy cream or coconut milk right before serving.
• Different Spuds: Try this stew over creamy polenta, soft cauliflower mash, or even a bed of rustic, buttered egg noodles.
• Add More Veggies: Toss in some sliced mushrooms with the initial veggies, or add a cup of frozen peas or corn at the end.

Olivia’s Final Thoughts & Kitchen Confessions

This recipe has been with me through thick and thin—it’s been my budget-saver, my crowd-pleaser for potlucks, and my ultimate comfort food after a long day. It’s evolved over time; the soy sauce for umami was a game-changer I discovered after reading about flavor science, and the smoked paprika addition came from a happy accident when I grabbed the wrong jar!

I’ll let you in on a little secret: I am notorious for forgetting to remove the bay leaves. I can’t tell you how many times I’ve served this and someone kindly points out the bay leaf hiding in their bowl. We just call it “finding the lucky charm” now. So, if you forget, don’t sweat it! It’s all part of the homemade charm. This dish is meant to be forgiving, just like a good friend. I hope it finds a special place in your recipe rotation and creates many warm memories in your kitchen, too.

Your Questions, Answered!

Q: Can I make this recipe in a slow cooker or Instant Pot?
A: Absolutely! For the slow cooker: Sauté the onions, carrots, and celery first for the best flavor (this step is worth it!), then add everything except the mashed potato ingredients to the slow cooker. Cook on low for 6-8 hours or high for 3-4 hours. For the Instant Pot: Use the sauté function for the veggies, then add the rest of the stew ingredients. Cook on high pressure for 15 minutes, with a natural pressure release for 10 minutes. Make the mashed potatoes separately while the stew cooks.

Q: My stew is too thin/watery. How can I thicken it?
A: No problem! The easiest way is to let it simmer uncovered for an extra 10-15 minutes to reduce. If you’re in a hurry, you can make a quick slurry: mix 1 tablespoon of cornstarch with 2 tablespoons of cold water until smooth. Stir this into the simmering stew and cook for another 2-3 minutes until thickened.

Q: Can I freeze the leftovers?
A: The lentil stew freezes beautifully for up to 3 months! Let it cool completely before transferring to airtight containers. I don’t recommend freezing the mashed potatoes, as they can become grainy and watery upon thawing. It’s best to make a fresh batch of potatoes when you reheat the stew.

Q: I only have red lentils. Can I use those?
A: You can, but be aware that red lentils break down much faster and create a softer, creamier stew. They will only need about 15-20 minutes of cooking time. The texture will be different, but it will still be delicious!
