Ingredients for Sausage And Lentil Soup

Here’s everything you’ll need to make this comforting soup (and trust me, it’s worth every ingredient!):

• 6 strips bacon, cut into small pieces (this is the flavor base – don’t skip it!)
• 16 ounces Italian sausage (casings removed if using links)
• 1 medium onion, chopped finely (about 1 cup)
• 2 sticks celery, chopped finely (about 1/2 cup)
• 1 medium red bell pepper, chopped finely (about 3/4 cup)
• 4 cloves garlic, minced (or 1 tablespoon from the jar)
• 6 cups chicken broth (low-sodium works great here)
• 1 (15 ounce) can tomato sauce (plain, not seasoned)
• 1.5 cups dry green or brown lentils, rinsed (no need to soak!)
• 1/2 teaspoon dried oregano (rubbed between your fingers to wake it up)
• 1/4 teaspoon crushed red pepper flakes, or to taste (for a little kick)
• Salt & pepper, to taste (wait until the end to adjust)

Ingredient Notes

Italian sausage adds amazing flavor, but you can use turkey sausage if you prefer. Just bump up the spices! Green lentils hold their shape best, but brown work too (just cook 30 mins less). No red bell pepper? Carrots make a great swap. And about that bacon fat – yes, we’re keeping some in the pan. That’s where the magic starts!

How to Make Sausage And Lentil Soup

Okay, let’s get cooking! This sausage and lentil soup comes together in three simple phases – browning the meats, sautéing the veggies, then letting the slow cooker work its magic. The key is taking your time with each step to build those deep, rich flavors. Don’t rush the browning – those crispy bits at the bottom of the pan are liquid gold for flavor! I like to start this soup in the morning so it’s ready by dinner, filling the house with the most incredible aroma all day.

Step-by-Step Instructions

1. Brown the bacon: In a large skillet over medium-high heat, cook the bacon pieces until crispy (about 10 minutes). Transfer to a paper towel-lined plate, but leave that glorious bacon fat in the pan!
2. Cook the sausage: Add the Italian sausage to the same skillet, breaking it up with a wooden spoon as it browns (7-8 minutes). When it’s nicely browned with some crispy edges, transfer it to join the bacon.
3. Sauté the veggies: Leave about 2 tablespoons of fat in the skillet (drain excess if needed). Add onion, celery, and red bell pepper, cooking until softened and lightly browned (5-7 minutes). Stir in the garlic just until fragrant (30 seconds).
4. Combine in slow cooker: Transfer the veggie mixture to your slow cooker. Add the cooked bacon, sausage, chicken broth, tomato sauce, lentils, oregano, and red pepper flakes. Give it a good stir!
5. Cook low and slow: Cover and cook on HIGH for 3-4 hours or LOW for 6-8 hours. The lentils should be tender but not mushy when done.
6. Final touches: Taste and adjust salt and pepper. For a thicker soup, blend about 1 cup with an immersion blender (or mash some lentils against the pot).

See those brown bits stuck to the skillet after cooking the meats? That’s flavor gold! Be sure to scrape them up when adding the broth – they’ll dissolve into the soup and make it extra delicious.

Tips for the Best Sausage And Lentil Soup

After making this soup dozens of times, here are my can’t-live-without tips:

• Brown it right – That golden crust on the sausage isn’t just pretty, it’s packed with flavor. Don’t rush this step!
• Spice to your taste – Start with 1/4 tsp red pepper flakes, then add more at the end if you want extra heat
• Thicken it up – For a heartier texture, blend about a cup of the soup right in the pot
• Rest before serving – Letting it sit 10 minutes off heat helps flavors meld beautifully

Oh, and that bacon fat? Liquid gold for flavor – don’t you dare drain it all!

Serving Suggestions for Sausage And Lentil Soup

This soup practically begs for a hunk of crusty bread to soak up all that delicious broth – I’m partial to a warm baguette or garlic toast. For weeknights, I’ll often pair it with a simple green salad tossed with lemon vinaigrette. Don’t forget the Parmesan! A generous sprinkle adds the perfect salty finish. It’s ideal for cozy family dinners, but I’ve also packed it in thermoses for fall picnics. Honestly, any occasion tastes better with a bowl of this comforting soup.

Storage and Reheating

This soup keeps like a dream! Store leftovers in an airtight container in the fridge for 3-4 days – the flavors actually get better as they mingle. For longer storage, freeze portions for up to 3 months (just leave a little room for expansion). When you’re ready to eat, reheat gently on the stovetop or in the microwave, adding a splash of broth if it thickens too much. Pro tip: Freeze individual portions for instant comfort food whenever the craving hits!

Sausage And Lentil Soup FAQs

What’s the best sausage for lentil soup?
Italian sausage (mild or hot) gives the most flavor, but any ground sausage works. I’ve used turkey sausage too – just add extra fennel and garlic powder to mimic Italian flavors. Avoid breakfast sausage though; the sweetness clashes with the savory soup.

How long do lentils take to cook in soup?
In the slow cooker, they need 3-4 hours on HIGH or 6-8 on LOW. Green lentils hold their shape best. If using brown lentils, check 30 minutes earlier as they soften faster. You want them tender but not mushy!

Can I make substitutions?
Absolutely! No celery? Use carrots. Out of red bell pepper? Try diced tomatoes. Vegetarian? Skip the meat and use smoked paprika for that bacon-like depth. The soup is very forgiving. For more vegetarian options, see our easy vegetarian lentil meatballs recipe.

How long does it keep?
3-4 days in the fridge – the flavors actually improve! Freeze for up to 3 months. Just reheat gently with a splash of broth if it thickens too much.
