Step-by-Step Instructions

1. Add Base Ingredients to Crockpot

Place diced potatoes, broccoli, onion, celery, and garlic into the slow cooker. Pour in broth, milk, thyme, smoked paprika, salt, and pepper. Stir to combine.

2. Cook Low and Slow

Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until potatoes are very tender and broccoli is soft.

3. Thicken the Soup

• In a small bowl, whisk cornstarch with cold water until smooth.
• Stir slurry into the hot soup. Cover and cook on HIGH for 15–20 minutes, until slightly thickened.

4. Blend (Optional but Recommended)

• For a creamy texture: Use an immersion blender to partially blend the soup (leave some chunks for texture).
• For a smooth bisque: Transfer 2–3 cups to a blender, blend until smooth, then return to pot.
• Skip blending for a chunkier, rustic soup.

5. Add Cheese & Butter

• Turn slow cooker to WARM or OFF.
• Stir in shredded cheddar and butter until melted and smooth. Do not boil—high heat can cause cheese to seize or become grainy.
• Taste and adjust seasoning (more salt, pepper, or a splash of hot sauce).

6. Serve

Ladle into bowls. Top with extra cheddar, crispy bacon, sliced green onions, or a dollop of sour cream. Serve with crusty bread or oyster crackers.

Pro Tips for Perfect Soup Every Time

• Freshly Shred Cheese: Pre-shredded cheese contains anti-caking agents that prevent smooth melting.
• Yukon Gold Potatoes: Naturally buttery and creamy—ideal for soups. Russets work but can be grainier.
• Don’t Overcook Broccoli: If using fresh, add it in the last 30 minutes on HIGH to retain color and texture (optional step for brighter green).
• Dairy Sensitivity: Add milk and cheese at the end to prevent curdling.
• Too Thick? Stir in extra broth or milk. Too Thin? Simmer uncovered on HIGH for 20 minutes or add more slurry.
• Make-Ahead: Cook base (without dairy/cheese) up to 2 days ahead. Add milk and cheese when reheating.

Creative Variations for Every Diet & Craving

1. Gluten-Free: Cornstarch is GF—just ensure broth is certified GF.
2. Dairy-Free/Vegan: Use unsweetened almond or oat milk, vegan cheddar, and olive oil instead of butter.
3. Keto/Low-Carb: Swap potatoes for cauliflower; use heavy cream instead of milk.
4. Loaded Baked Potato Soup: Add cooked bacon, sour cream, and chives.
5. Spicy Southwest: Stir in 1 diced jalapeño + ½ tsp cumin + top with avocado.
6. Ham & Broccoli: Add 1 ½ cups diced cooked ham with the potatoes.

Frequently Asked Questions (FAQs)

Q: Can I use frozen broccoli?
A: Yes! Add it at the beginning—it thaws and cooks perfectly in the slow cooker.

Q: Why is my soup grainy?
A: Likely causes: Pre-shredded cheese, boiling after adding cheese, or low-fat dairy. Use full-fat, freshly shredded cheese and stir off-heat.

Q: Can I freeze this soup?
A: Yes, but without dairy. Freeze the base (potatoes, broccoli, broth). Thaw, reheat, then stir in milk and cheese fresh.

Q: Can I make it on the stovetop?
A: Absolutely! Simmer covered for 20–25 minutes until potatoes are tender, then proceed with thickening and cheese.

Q: How long does it keep in the fridge?
A: Store in an airtight container for up to 4 days. Reheat gently on the stove over low heat.
