The Story Behind the Crockpot Potato Broccoli Cheddar Soup
There’s something undeniably comforting about a bowl of potato soup—it’s nostalgic, hearty, and universally loved. But when you add broccoli and sharp cheddar to the mix, it transforms into a dish that’s both wholesome and indulgent. This Crockpot Potato Broccoli Cheddar Soup is inspired by classic baked potato soup and the beloved broccoli cheddar combo, but with a slow-cooker twist that makes it effortless.
Did you know that broccoli is part of the cabbage family and was first cultivated in Italy over 2,000 years ago? It’s a nutritional powerhouse, packed with fiber, vitamins C and K, and even protein. And when paired with potatoes—one of the most versatile and budget-friendly ingredients—you get a soup that’s as nutritious as it is delicious.
This recipe is perfect for:
- Busy weeknights (just dump the ingredients and let the crockpot work).
- Meal preppers (it reheats beautifully).
- Families with picky eaters (who can resist cheesy potatoes?).
Why You’ll Love This Crockpot Potato Broccoli Cheddar Soup

1. Creamy, Cheesy, and Veggie-Packed Perfection
This soup is the ultimate comfort food upgrade. The sharp cheddar melts into a velvety broth, while the potatoes break down slightly to thicken the soup naturally. The broccoli adds a pop of color and freshness, making each bite balanced.
Pro Tip: For extra creaminess, blend half the soup—this creates a luxurious texture while keeping some potato chunks for heartiness.
2. Costsaving Comfort (Without the Restaurant Markup!)
A bowl of broccoli cheddar soup at a café or bakery can cost $8–$12, but making it at home cuts that down to $2–$3 per serving. Plus, you avoid preservatives and control the ingredients.
Budget Breakdown (Serves 8):
- Potatoes: $1.50
- Broccoli: $2.00
- Cheese: $3.00
- Broth & Cream: $2.50
- Total: ~$9.00 ($1.12 per serving!)
3. Toppings Galore: Make It Your Own
The best part? Customization! Try these topping ideas:
- Classic: Crumbled bacon, extra cheddar, green onions.
- Crunchy: Toasted breadcrumbs, crushed crackers, or roasted chickpeas.
- Fresh: Diced avocado, cherry tomatoes, or a dollop of Greek yogurt.
Ingredients for Crockpot Potato Broccoli Cheddar Soup
(Serves 6–8)
Base Ingredients
- 4 medium potatoes (about 2 lbs / 900 g) – Russets or Yukon Gold work best.
- 3 cups (720 ml) broccoli florets – Fresh or frozen (no thawing needed!).
- 1 medium onion – Yellow or white for sweetness.
- 3 cloves garlic – Minced for maximum flavor.
- 4 cups (960 ml) chicken or vegetable broth – Low-sodium recommended.
- 1 tsp salt – Adjust to taste.
- ½ tsp black pepper – Freshly cracked for best flavor.
- ½ tsp smoked paprika – Optional, but adds depth.
For Creaminess & Richness
- 1 cup (240 ml) heavy cream or half-and-half – Evaporated milk works too.
- 2 cups (200 g) shredded sharp cheddar cheese – Freshly grated melts smoother.
- 2 tbsp all-purpose flour – For thickening (or cornstarch for gluten-free).
- 2 tbsp butter – Optional, but adds silkiness.
Garnishes (Optional but Highly Encouraged)
- Crumbled bacon – Because everything’s better with bacon.
- Extra shredded cheddar – For that Instagram-worthy cheese pull.
- Chopped green onions – Freshness to balance richness.
Step-by-Step Instructions
1. Prep the Ingredients (15 Minutes)
- Peel and dice potatoes into 1-inch cubes (smaller pieces cook faster).
- Chop broccoli into bite-sized florets (stems can be peeled and diced too!).
- Dice onion and mince garlic – A fine dice ensures even flavor distribution.
2. Layer in the Crockpot (5 Minutes)
- Add potatoes, broccoli, onion, garlic, broth, salt, pepper, and smoked paprika to the crockpot.
- Stir gently to combine.
Why layering matters: Potatoes at the bottom cook more evenly, while broccoli on top stays vibrant.
3. Cook Low and Slow (6–8 Hours on Low or 3–4 Hours on High)
- Cover and cook until potatoes are fork-tender.
- Avoid stirring during cooking to prevent breaking the broccoli.
Slow Cooker vs. Instant Pot: A slow cooker yields deeper flavor, but an Instant Pot can speed this up (30 minutes on high pressure).
4. Blend for Creaminess (Optional—5 Minutes)
- Immersion blender method: Pulse until semi-smooth (leave some texture).
- Blender method: Blend 2–3 cups of soup, then return to the pot.
Texture Tip: For a chunkier soup, skip blending and mash lightly with a potato masher.
5. Add Cream and Cheese (10 Minutes)
- Stir in heavy cream (whisk in flour first if thickening).
- Gradually add cheese while stirring to prevent clumping.
- Finish with butter for extra richness.
Cheese Science: Shred your own cheese—pre-shredded has anti-caking agents that can make the soup grainy.
What to Serve With Crockpot Potato Broccoli Cheddar Soup
1. Bread & Crackers
- Crusty sourdough – Perfect for soaking up every last drop.
- Garlic bread – Because garlic makes everything better.
- Cheese crackers – Adds a fun crunch.
2. Fresh Salads
- Simple Arugula Salad – Peppery greens balance the richness.
- Apple Walnut Salad – Sweet and crunchy contrast.
3. Protein Sides
- Grilled chicken – For a heartier meal.
- Pan-seared sausage – Adds a smoky touch.
Top Tips for Perfecting Your Crockpot Potato Broccoli Cheddar Soup
Ingredient Swaps & Tricks
- Dairy-Free? Use coconut milk and nutritional yeast for a cheesy flavor.
- Gluten-Free? Thicken with cornstarch (1 tbsp mixed with 2 tbsp water).
- Extra Veggies: Add carrots, cauliflower, or spinach.
Avoid Common Mistakes
- Overblending – Can make the soup gluey.
- High Heat When Adding Cheese – Causes separation (low and slow is key!).
- Underseasoning – Potatoes need salt! Taste before serving.
Storing and Reheating Tips
Refrigerating (Up to 3 Days)
- Cool completely before storing in airtight containers.
- Reheat gently on the stove with a splash of broth or milk.
Freezing (Up to 2 Months)
- Freeze in portion-sized bags (lay flat to save space).
- Thaw overnight in the fridge before reheating.
Pro Tip: If the soup separates after freezing, blend briefly when reheating.
