3-4 Quart	6-7 hours	3-4 hours	Creamy with distinct broccoli pieces

Step-by-Step Slow Cooker Preparation

Follow these precise steps for the best broccoli cheddar soup slow cooker instructions that guarantee perfect results every time:

1. Sauté aromatics: In a skillet over medium heat, melt butter and cook onions until translucent (5 minutes). Add garlic and cook 1 minute more. This foundational step builds flavor depth that simmering alone cannot achieve.
2. Create roux: Sprinkle flour over sautéed mixture, stirring constantly for 2 minutes to eliminate raw flour taste. Gradually whisk in 1 cup broth until smooth.
3. Transfer to slow cooker: Pour roux mixture into crockpot with remaining broth, broccoli, mustard powder, salt, and pepper. Stir gently to combine.
4. Cook patiently: Cover and cook on LOW for 6-8 hours (or HIGH for 3-5 hours depending on size—see timing chart). Avoid opening the lid frequently as this adds 20-30 minutes to cooking time each time.
5. Add dairy last: During the final 30 minutes, stir in milk/cream and gradually add cheese in small handfuls, allowing each addition to melt completely before adding more. This prevents cheese clumping—a common issue in how long to cook broccoli cheddar soup in slow cooker attempts.
6. Final adjustment: Taste and adjust seasoning. For thicker soup, mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir in, cooking 15 minutes more.
