Thick and Creamy Broccoli Cheddar Soup That Warms The Belly

When the weather is cold and the days are busy, there is nothing more satisfying than a bowl of steaming soup. This thick and creamy broccoli cheddar soup will hit the spot!

Before your days gets packed, prep this soup. Toss in frozen broccoli, a diced onion (or dehydrated onion if you’re really in a hurry), plus a shredded carrot. Dump in broth and seasonings. Done!

Bonus: since there is no meat in this recipe, you can set your crockpot on a delayed start timer. Prepping this at 7am for 6pm dinner? Set the timer for 12 or 1.

My favorite part comes just before serving. There is something soothing about watching cornstarch dissolve and thicken. Maybe it’s my mad inner scientist or  need to analyze everything. No matter the reason, the cornstarch and cheese work wonders at thickening this broccoli soup. Plus, it wouldn’t be broccoli cheddar soup without the cheese! (Yes, one time I made this soup and forgot the cheese. Don’t make the same mistake, it doesn’t taste as satisfying.)

One day I’ll attempt to make a bread bowl to pair with this yummy dinner. (If you have a great recipe for this, please share in the comments below!) But presently I serve it with crusty french bread or a caesar salad. Also, this reheats well, making it an excellent leftover!
