2 cups shredded sharp cheddar cheese

1/4 cup water
1/2 tsp salt

Step-by-Step Instructions

Prep the Vegetables

Start by dicing one medium yellow onion and mincing three cloves of garlic. If using fresh broccoli, cut it into small florets (about 4 cups).

You don’t need to be precise here — the slow cooker will break them down. If using frozen broccoli, thaw it first and drain any excess water.

This step takes about 5 minutes and is the most hands-on part of the whole recipe. Toss the onion, garlic, and broccoli into the slow cooker.

Add Broth and Seasonings

Pour 4 cups of low-sodium chicken or vegetable broth over the vegetables. Add 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1/4 teaspoon paprika.

Give everything a quick stir to combine. The paprika adds a subtle warmth without any heat, making it kid-friendly.

Cover the slow cooker and set it to LOW for 4 hours or HIGH for 2 hours. The broccoli should be very tender when pierced with a fork.

Blend the Soup Base

Once the broccoli is tender, turn off the slow cooker. Use an immersion blender to puree the soup until smooth.

If you don’t have an immersion blender, carefully transfer the soup in batches to a regular blender. Be sure to remove the center cap from the blender lid and cover with a towel to let steam escape.

Blend until velvety. This step creates that silky texture without any extra cream or flour.

Make the Creamy Cheese Base

In a small bowl, whisk together 1/4 cup cornstarch and 1/4 cup cold water until smooth. This slurry will thicken the soup without lumps.

Add the slurry, 1 cup heavy cream, and 8 ounces of softened cream cheese (cut into cubes) to the blended soup. Stir well.

The residual heat from the soup will start melting the cream cheese. Turn the slow cooker back to HIGH and cover for 10 minutes.

Add the Cheddar and Finish

After 10 minutes, remove the lid and stir until the cream cheese is fully incorporated and the soup is smooth. Add 2 cups of shredded sharp cheddar cheese in handfuls, stirring after each addition until melted.

Pro tip: buy a block of cheddar and shred it yourself — pre-shredded cheese often contains anti-caking agents that can make the soup grainy. Once all cheese is melted, taste and adjust seasoning if needed.

Serve hot.

Tips and Tricks for Perfect Soup

Skip the Pre-Shredded Cheese

For the smoothest, creamiest soup, always shred your own cheddar from a block. Pre-shredded cheese is coated with cellulose and starches that prevent clumping but also prevent smooth melting. It takes an extra 2 minutes and makes a huge difference in texture.

Control the Thickness

If your soup is too thick after adding the cheese, stir in a splash of milk or broth until it reaches your desired consistency. If it’s too thin, mix another tablespoon of cornstarch with an equal amount of water and stir it in, then cook on HIGH for 10 more minutes.

Make It a Meal

Turn this soup into a complete dinner by adding cooked shredded chicken or diced ham along with the cheese. You can also stir in cooked pasta or rice after blending for a heartier version. Just remember that pasta and rice will continue to absorb liquid, so you may need to add extra broth when reheating leftovers.

Recipe Variations

Add 2 cups cooked shredded chicken for protein.
Use a mix of cheddar and Monterey Jack for milder flavor.
Stir in 1 cup cooked elbow macaroni for broccoli cheddar pasta soup.
Swap broccoli for cauliflower for a different twist.
Add 1/2 teaspoon red pepper flakes for a spicy kick.

Frequently Asked Questions

Can I use frozen broccoli?

Yes, frozen broccoli works perfectly. Thaw it first and drain any excess water to avoid thinning the soup.

Add it directly to the slow cooker without extra prep. Frozen broccoli may cook a bit faster, so check for tenderness after 3 hours on LOW.

How do I store leftovers?

Store leftover soup in an airtight container in the refrigerator for up to 4 days. The soup will thicken as it sits, so when reheating, add a splash of milk or broth to restore the desired consistency. Reheat on the stovetop over medium-low heat, stirring occasionally, or in the microwave in 30-second intervals.

Can I freeze this soup?

Yes, but keep in mind that dairy-based soups can change texture after freezing. For best results, cool the soup completely, then freeze in a freezer-safe container for up to 3 months.

Thaw overnight in the refrigerator and reheat gently. If the soup seems grainy, whisk in a tablespoon of heavy cream while reheating.

Can I make this soup dairy-free?

Yes, you can substitute the heavy cream with full-fat coconut milk, use dairy-free cream cheese, and replace the cheddar with a vegan shredded cheese. The flavor will be slightly different, but the texture will still be creamy. Use a dairy-free butter and flour roux if you prefer not to use cream cheese.

Summary

This crock pot broccoli cheddar soup is a lifesaver for busy parents. With minimal prep, simple ingredients, and creamy results, it’s a weeknight winner the whole family will love.
