Soups & Stews
This bacon red lentil soup delivers the perfect marriage of smoky, crispy bacon and tender lentils in every spoonful. The secret lies in rendering the bacon perfectly—crispy edges that crumble into the broth—while letting the lentils develop their natural earthiness.

What you’ll end up with is a soup that’s creamy yet light, with lentils that soften just enough to release their natural sweetness.

The bacon is non-negotiable here. Thick-cut is key—it renders slowly, giving you those perfect crispy edges that crumble into the soup. Costco sells it in bulk, or grab the pre-sliced stuff at Trader Joe's for convenience. The red lentils? Bob's Red Mill or any store brand works, but avoid the pre-washed kind—it loses texture. For the tomatoes, Muir Glen is my go-to canned brand—no salt added, no funny aftertaste. The miso paste? White miso is milder and sweeter, but red miso
No thick-cut bacon? Regular bacon works in a pinch, but you'll need to watch it closely to avoid burning. Short on thyme? Fresh oregano at the same amount gives a similar vibe. The vegetable broth can be swapped for chicken broth if you're not strict veggie, but the miso adds enough umami that it won't taste off. The apple cider vinegar might seem odd, but it cuts through the richness—trust me, it balances everything. For the smoked paprika, Penzeys has the best quality, but regular grocery store brands are fine if they're fresh. This soup tastes even better the next day—make a double batch if you can. Keeps for 5 days in the fridge, or freeze for 3 months. I portion it into containers with a layer of broth on top to keep everything moist. The bacon bits? Save those for garnish—they're the star of the show. Fresh thyme wilts fast, so store it wrapped in damp paper towels in the fridge.

Step-by-step instructions for bacon red lentil soup
Here's how to create a rich, smoky-sweet soup with perfectly crispy bacon edges.
Cook the Bacon Until Crispy
Place the 6 oz thick-cut bacon in a large, deep pot over medium heat. Cook undisturbed for 8-10 minutes until the edges become deep golden brown and crispy. I press down gently on the bacon during the first minute—this prevents it from curling and ensures even contact with the pan.
Once the bacon is crispy, use a slotted spoon to transfer it to a paper towel-lined plate. Leave the rendered fat in the pot—this is where all the flavor lives. If you're worried about excess fat, you can drain most of it, but I like to keep about 2 tablespoons for cooking the onions. The bacon should be crisp enough to hold its shape when lifted with tongs.
Sauté Onions and Garlic for Depth
Add 2 tablespoons extra-virgin olive oil to the pot with the bacon fat and set it over medium heat. Toss in the diced yellow onion and cook for 5-6 minutes until softened and light golden brown. This step builds the foundation of the soup's flavor—don't rush it.
Stir in the 3 minced garlic cloves and cook for another 30 seconds until fragrant. Here's the thing—garlic burns fast, so keep an eye on it. As soon as you smell that nutty aroma, it's time to move on. Add 1 teaspoon smoked paprika and stir for 10 seconds to toast it lightly—this deepens the smoky flavor without overpowering.
Build the Flavor Base
Pour in the 14.5 oz diced tomatoes and stir to combine with the onions. Let the mixture simmer for 3 minutes until the tomatoes break down slightly. This step helps develop the soup's rich, tangy base. Add the 1 cup red lentils, 4 cups vegetable broth, and 1 tablespoon white miso paste, stirring well to dissolve the miso completely.
Bring the mixture to a gentle boil, then reduce heat to low and let it simmer for 20 minutes. You'll see the lentils begin to soften and the soup thicken slightly. I stir occasionally, but not constantly—this prevents the lentils from breaking down too much and turning mushy. The soup should be smooth but still have some texture from the lentils.
Finish with Brightness and Crispy Bacon
Stir in the 0.25 cup fresh thyme leaves, 0.5 teaspoon salt, and 0.25 teaspoon black pepper. Add the 1 tablespoon apple cider vinegar and the crispy bacon you set aside earlier. Simmer for another 5 minutes to let the flavors meld together. The vinegar brightens the soup, cutting through the richness of the bacon and miso.
Taste and adjust the seasoning if needed. The soup should be balanced—smoky from the bacon and paprika, sweet from the lentils, and bright from the vinegar. If it's too thick, add a splash of water or broth to reach your desired consistency. Serve immediately, garnished with extra crispy bacon bits if you're feeling fancy.
Pro Tips For Making Bacon Red Lentil Soup
- CRISP THE BACON LOW: Thick-cut bacon needs patience—cook it slow over medium heat until the edges turn golden and the fat renders just enough to coat the pan. High heat burns the sugar; you want caramelized edges, not smoke alarms. Save the crispy bits for garnish—they’re the real flavor bombs in this soup.
- SOAK THE LENTILS FIRST: Red lentils cook fast, but skipping the 10-minute soak in warm water means they’ll turn mushy and split into paste. Drain before adding them to the pot—this keeps the soup’s texture thick and hearty, not gluey. (Yes, even if you’re impatient like me.)
- SWEAT THE ONIONS RIGHT: Don’t rush the onion and garlic step—cook them over medium-low heat until the onions are translucent and the garlic smells almost burnt but isn’t. This builds flavor without burning, and it’s the base everything else clings to. Crowd the pan, and you’ll steam instead of caramelize.
- SAVE THE TOMATO JUICE: When adding diced tomatoes, resist the urge to dump in the can liquid—it dilutes the soup’s richness. Instead, strain the tomatoes first, then add just enough juice to loosen the lentils. The soup will be thicker, creamier, and way more satisfying. (Your future self will notice.)
Common mistakes when making this dish
Overcooking the Lentils
Red lentils cook fast—usually 15-20 minutes—but they turn to mush if you overcook them. I’ve seen this happen when people walk away from the stove or forget to stir occasionally. The goal is tender but still holding shape. If your lentils look like glue, you’ve gone too far. 🌾
Skipping the Bacon Fat
That rendered bacon fat is flavor gold—don’t drain it! I’ve made this mistake when trying to cut fat, and the soup loses its depth. Keep at least 2 tablespoons of fat in the pot for sautéing onions. If you’re really worried, drain most of it but leave some behind.
Ignoring the Vinegar
The 1 tablespoon apple cider vinegar might seem small, but it’s crucial for balancing the rich flavors. Without it, the soup can taste flat or overly heavy. I’ve tasted versions without vinegar, and they’re missing that bright, tangy lift that makes the dish sing. 🍏
Using Thin-Cut Bacon
Thin-cut bacon cooks too fast and won’t get crispy edges. If you only have thin-cut, cook it at low heat for 12-15 minutes, stirring occasionally. Otherwise, the bacon will burn before it crisps. Trust me, the texture difference is night and day.
Not Tasting as You Go
Seasoning soup is an ongoing process. I’ve ruined batches by adding all the salt at the start—then realizing it’s too salty by the end. Taste after adding the lentils, then again at the finish. Adjust gradually with ½ teaspoon salt increments until it’s perfect.
Rushing the Bacon Crisp
Patience is key with bacon. If you crank the heat too high, the edges won’t crisp properly—they’ll just turn greasy. Cook at medium heat and let it work its magic. The first 8 minutes are the most critical—don’t rush them! 🥓

Frequently asked questions
Can I substitute chicken broth for vegetable broth?
The recipe works beautifully with chicken broth—it adds a richer depth that pairs perfectly with the bacon. Just reduce the miso to ½ tablespoon since chicken broth already has umami. For extra flavor, use homemade broth or low-sodium store-bought. The soup will taste even more hearty and satisfying.
How do I make this soup spicier?
Add ½ teaspoon cayenne pepper or 1 teaspoon hot paprika when sautéing the onions. For heat lovers, stir in 1 chopped chipotle pepper in adobo with the tomatoes. Remember, you can always add more spice at the end—just don't overdo it with vinegar afterward, as it can mute the heat.
Can I make this soup in an Instant Pot?
Cook the bacon separately (as crispy as possible), then sauté onions and garlic in the pot. Add all remaining ingredients except the bacon and thyme. Seal and cook on high pressure for 6 minutes, then quick-release. Stir in the crispy bacon and thyme at the end. The Instant Pot version finishes in 25 minutes total—perfect for busy weeknights.
Why did my lentils turn mushy?
Red lentils cook fast—overcooking is the usual culprit. They're done when tender but still holding shape (15-20 minutes max). Stir occasionally and taste at 15 minutes to check. If they're still firm, simmer 2-3 more minutes. Never walk away from the stove! The vinegar at the end won't fix mushy lentils, but it will help balance flavors.
What's the best way to reheat leftovers?
Reheat gently on the stove over low heat with 2 tablespoons water or broth to prevent drying. Stir frequently and add more liquid if needed. Microwave in 30-second bursts, stirring between each, until hot. The bacon bits will stay crispy if reheated quickly—just sprinkle fresh ones on top before serving for that restaurant-quality touch.
