Oriana’s Thoughts On The Recipe
Whenever the weather turns cold, I reach for recipes that feel warm, grounding, and safe for every allergy kid at my table. This Lentil and Butternut Squash Soup does exactly that. It’s naturally egg-free, dairy-free, and gluten-free which means I don’t have to make substitutions or worry about separate meals for my kids—just one big pot we can all share.
There’s something so comforting about the smell of lentils simmering with sweet squash and spices. It reminds me that simple food, made with intention, is often the most nourishing. Lentils also cook quickly, which makes this an easy win on nights when I want something wholesome without the stress. And the best part? My family loves it—especially on rainy days when everyone wants something warm and filling.
Why You’ll Want to Try My Recipe
Ingredients You’ll Need, Substitutions & Notes
Please check the recipe card at the bottom of the post for exact quantities and detailed instructions (scroll down).
- Oil: You can use olive oil, canola, or any oil of your preference.
- Veggies: You’ll need onion, garlic, mini sweet peppers, and butternut squash.
- Canned Tomatoes: I used Hunt’s® fire-roasted tomatoes.
- Lentils: You’ll need beluga black lentils and split red lentils. These black lentils are called beluga because of their resemblance to caviar. They have a warm, nutty flavor and keep their shape even during prolonged cooking. On the other hand, the red lentils, also called red ‘split’ lentils, are the sweetest of the lentils – to my mind, at least! They lose their firm texture while cooking, becoming a bit mushy. You can find beluga lentils at specialty gourmet stores, like Whole Foods, or here.
- Chicken broth: Homemade or store-bought. I recommend using low-sodium broth. For a vegetarian version, use vegetable broth.
- Spices & Seasonings: You’ll need ground cumin, dry oregano, smoked paprika, turmeric, bay leaf, salt, and black pepper.
- Cilantro: This is for garnishing, so it’s optional. You can use fresh parsley if you prefer.

Lentils. For this recipe, you can use black, red, green, brown, or yellow lentils, though the soup’s color will vary depending on which you choose.
Meat lovers. If you want to add extra protein to the soup, you can add some chopped sausage or smoked pork chops (our fave) when sautéing the veggies.

A squeeze of fresh lemon juice when serving takes this soup to the next level!

This recipe was amazing!!! It gets even better as it sits in the fridge. Cooked over the weekend and finished eating today. Sooooo good. I made a couple of changes. My husband can’t eat garlic, so I omitted. Used pre-cooked lentils from Trader Joe’s and added toward the end so they didn’t get mushy. Also added a chopped carrot to the onion. Roasted the squash before adding toward the end and added some diced chicken for extra protein. I think this recipe would also be delicious exactly as written. Making again this week to freeze for later 🙂 Thanks!
Hello Debbie! It sounds like you nailed it. I love this recipe too. Thanks so much for trying my recipe and taking the time to come back and let me know.
Hun I’m new to both your site and instant pot. I got for my birthday. I have to agree your pics are very nice. Not finding black Lentils but have both red and brown in my pantry. Can I sub those?
Hello Debb! You can use any lentils you have on hand. I Like to use black lentils because they hold their shape after cooking. Thanks for your interest in my recipe. ?
There are so many things to love about this stew. The vegetables and easy of it are just a few! Pinned. 🙂
Thanks Laura!! With 2 little ones “EASY” it’s a must for me. Thanks for stopping by =)
Desde muy pequeñita mi mama me enseño a comer lentejas en diferentes preparaciones. Por eso es que me encanta, en sopas, guisadas, en crema, sopa, en arroz con lentejas, ay! que ricas son! Estas se ven riquisimas.
Las lentejas son muy latinas!! Mi mama todavía las cocina mucho. Esta version es deliciosas. Espero que te guste.
This looks so comforting! I admittedly ignore lentils far too much. The ones in my pantry have probably been sitting there for over a year. Need to get on that!
Gina – I used to ignore lentils as well, until I discovered beluga lentils! Their texture is so much better. Thanks for stopping by.
Que provocativas y ricas estan las lentejas, me encantan porque son muy saludables y aportan hierro y fibra.
Así es Mayito… saludables y deliciosas!! Gracias por tu visita =)
I just love this recipe! Your photos are gorgeous and an inspiration for this dish!
