Why This Broccoli Cheddar Soupe Recipe Works
- Set‑and‑forget method: Layer, cook, stir—your slow cooker handles the heavy lifting while you get on with your day.
- Ultra‑creamy texture: Velveeta melts smoothly and resists splitting; a touch of flour adds body for that velvety mouthfeel.
- Balanced flavor: Onion and garlic build savory depth; cream soups add richness and umami with almost zero effort.
- Flexible and forgiving: Frozen broccoli holds texture better over long, moist cooking; potatoes naturally thicken as their starches gelatinize.
Tip: For safe, worry‑free reheating later, keep an eye on temperatures. See the official guidance on safe minimum temps and reheating practices here: safe minimum temperatures for cooked foods
Key Ingredients Of The Broccoli Cheddar Soup (and Smart Swaps)
- Frozen broccoli florets (32 oz/900 g): Hold structure better than fresh during long cooks. If using fresh, add late (see Tips).
- Idaho (Russet) potatoes (2), peeled and diced: Starchy, fluffy potatoes release starch for natural thickening.
- Cream of chicken + cream of mushroom (1 can each, 10.5–10.75 oz / ~300 g): Pantry‑friendly richness and body. For vegetarian, use two cans of mushroom.
- Yellow onion (1 small), thinly sliced; garlic (2 cloves), minced: Classic aromatic base.
- Chicken broth (14 oz/414 ml): Vegetable broth for vegetarian; bouillon works in a pinch.
- Butter (¼ stick/28 g): Adds gloss and roundness.
- Velveeta (1 block/16 oz/454 g), cubed: Seamless melt for that classic broccoli‑cheddar vibe. Prefer natural cheeses? See Tips below.
- Flour (1 tsp): A tiny amount helps bind; for gluten‑free, use 1½ tsp cornstarch.
- Salt and black pepper, to taste.
Cheese science note: Processed cheeses melt uniformly because of emulsifying salts that keep fat and water bound, preventing a greasy split. Learn more here: why some cheeses melt better than others.

- Sprinkle flour evenly over the top; dot with butter. Season lightly with salt and pepper.
Cook
- High: 4–5 hours, stirring 1–2 times; or Low: 7–8 hours.
- The potatoes should be tender and the broccoli cooked through.

Pro Tips for Silky, Creamy Results For The Broccoli Cheddar Soup
- Add cheese at the end: Melting in the final 20–30 minutes prevents separation or graininess.
- Control thickness: Lightly mash a few potato cubes against the pot wall before adding cheese for a thicker body.
- Using cheddar instead of Velveeta:
- Shred it yourself (pre‑shredded often contains anti‑caking starches that hinder melting).
- Remove heat and stir in cheese by the handful to avoid splitting.
- A tablespoon of cream cheese stabilizes natural cheddar beautifully.
- Fresh broccoli caution: Add fresh florets during the last 60–90 minutes on Low (or 30–45 minutes on High) so they stay tender‑crisp.
- Oil and splatter minimization: If you crisp bacon for topping, mind hot fat safety. Review deep‑frying safety basics many principles also help when sautéing toppings.
Make‑Ahead, Serving & Storage
- Make‑ahead: Load the crock insert the night before (except the broth). Refrigerate covered. Add broth before cooking and extend the cook time 30–45 minutes to account for the cold start.
- Refrigerate: Cool quickly; store 3–4 days in a sealed container.
- Reheat: Low and slow on the stovetop, stirring to prevent scorching. Add a splash of broth or milk to loosen if thick.
- Freeze: Dairy‑based soups can separate. If freezing, cook and cool the soup without the cheese; freeze up to 2–3 months. Reheat gently, then stir in cheese just before serving.
- Food safety targets: Reheat leftovers until steaming throughout. Aim for at least 74°C/165°F in the center for peace of mind. See cooking and reheating temps safe minimum temperatures for cooked foods
Variations & Substitutions
- Vegetarian: Use vegetable broth and replace cream of chicken with another can of cream of mushroom.
- Cheese swaps: Sharp cheddar, white cheddar, or a cheddar–Monterey Jack blend. Finish bowls with grated Parmesan for extra savoriness.
- Veggie boosters: Carrots, celery, or leeks (sauté first for sweetness and better texture).
- Spicy twist: Red pepper flakes, a dash of hot sauce, or minced jalapeño.
- Bacon lovers: Stir in crisped bacon just before serving for smoky crunch.
- Lighter option: Replace half the Velveeta with evaporated milk added in the last 20 minutes.
