Ingredients and Measurements

• 1 pound mild Italian sausage
• 2 pounds peeled butternut squash, diced into 1-inch cubes
• 1 medium yellow onion, chopped
• 1 medium Granny Smith or Honeycrisp apple, peeled and chopped
• 3 cloves garlic, minced
• 4 cups low-sodium chicken broth
• 1 teaspoon rubbed sage
• 1/2 teaspoon dried thyme
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon ground nutmeg
• 3/4 cup half-and-half

Slow-Cooker Cooking Steps

1. Brown sausage in a skillet over medium heat, breaking into small crumbles.
2. Pour off and discard excess fat from the skillet.
3. Add browned sausage, diced butternut squash, chopped onion, chopped apple, minced garlic, chicken broth, rubbed sage, dried thyme, salt, pepper, and nutmeg to the slow cooker and stir to combine.
4. Cover and cook on LOW for 5 1/2 to 6 hours, until the squash is very soft and tender.

5. Ladle out about 2 cups of the cooked soup (squash, broth, veggies) and blend until smooth with an immersion blender or in batches in a regular blender (vent lid slightly).

   

6. Stir the purée back into the slow cooker.
7. Stir in the half-and-half, cover, and cook on HIGH for 15 minutes until warmed through.
8. Taste and adjust salt and pepper as needed.
9. If the soup is too thin, cook uncovered on HIGH for 15–30 minutes or blend in more cooked squash; if too thick, stir in extra chicken broth.

Helpful Tips and Fixes

• Make sure to brown and drain the sausage well to keep the soup from turning greasy—this sheet-pan method for browning sausage and peppers shows how to render fat and get deep caramelization.
• If using a regular blender, work in batches with the lid slightly vented to avoid steam pressure.
• Start by blending just 2 cups of soup; if you like a creamier, thicker texture, blend more. For a quick example of using partial blending to add body, see how partial blending adds body in Zucchini Corn Chowder.
• Adjust salt and pepper at the end since sausage and broth salt levels can vary.
• If your soup feels too thin, cook it uncovered on HIGH for 15–30 minutes or blend in a bit more cooked squash. Too thick? Stir in extra chicken broth to loosen it up.

Flavor Swaps and Add-Ins

• Turn up the heat by swapping mild sausage for hot Italian sausage (as in Crockpot Lasagna Soup) or adding a pinch of cayenne pepper.
• For dairy-free, skip the half-and-half and swirl in one can of full-fat coconut milk at the end for creaminess.
• Go vegetarian by replacing sausage with 2 cups of cooked lentils or chickpeas and using vegetable broth instead of chicken.
• Boost nutrition by stirring in a couple handfuls of baby spinach or kale during the last 10 minutes of cooking.
• Mix up the flavor by using apple sausage or smoked sausage for a lightly smoky, sweet twist.

Storage and Reheating Guide

• Refrigerate: Let the soup cool to room temperature, then store it in an airtight container for 3–4 days.
• Freeze: For best texture, cool completely and freeze in airtight containers or freezer-safe bags for up to 3 months. If you can, hold off on adding the half-and-half before freezing—add it fresh when reheating.

• Reheat: Thaw overnight if frozen, then gently warm on the stovetop over low-to-medium heat, stirring occasionally. If you froze it without dairy, stir in the half-and-half near the end of reheating. Once hot, serve with a slice of Green Onion Zucchini Cheddar Quick Bread for an easy side.

Common Questions Answered

• Can I use frozen butternut squash? : Absolutely! Just cut the cooking time by about 30–60 minutes and check for tenderness since frozen squash softens quicker.
• Can I make this on the stovetop? : Yes, you can simmer everything covered on low for 30–40 minutes until the squash is tender, then blend part of the soup and finish with half-and-half. For a similar quick stovetop simmer-and-blend approach, see our Mexican Street Corn Soup.
• Can I substitute heavy cream? : Yes, heavy cream will make it richer and silkier; use the same amount or a little less if you want.
• How can I thicken the soup more? : Blend more of the cooked solids or simmer uncovered to reduce it down. You can also make a slurry with 1 teaspoon cornstarch plus 1 tablespoon cold water, stir it in, and bring to a simmer to thicken nicely. For an example of using partial blending to build body without starch, see the technique in our Summer Corn and Zucchini Chowder.
• Is it freezer-friendly with dairy? : It’s best to freeze without the half-and-half and add it fresh when reheating to keep the soup smooth and avoid separation.
