Ingredients
12 oz dry medium pasta shells
4 cups small fresh broccoli florets
3 cups vegetable broth
2 cups shredded sharp cheddar cheese, divided
1 cup whole milk or 2% milk
Optional (not counted in the 5 ingredients):
Salt and pepper to taste
Step-by-Step Instructions
Step 1: Prepare the Slow Cooker
Lightly spray the inside of a 4- to 6-quart slow cooker with nonstick cooking spray. This helps prevent sticking and makes cleanup much easier.
Step 2: Add the Pasta
Pour the dry pasta shells into the bottom of the slow cooker. Spread them into an even layer.
Step 3: Add the Broth
Pour the vegetable broth over the pasta, making sure most of the shells are submerged.
Gently press down any pasta sitting above the liquid so it cooks evenly.
Step 4: Layer the Broccoli
Scatter the fresh broccoli florets evenly over the top of the pasta.
Do not stir yet.
The broccoli should sit in a visible layer on top — this allows it to steam gently while the pasta cooks underneath.
Step 5: Cook on HIGH
Cover with the lid and cook on:
HIGH for 1½ to 2 hours
Start checking at 1½ hours, as slow cookers vary. The pasta should be just tender, and most of the liquid should be absorbed.
Avoid overcooking, as pasta can become too soft quickly.
Step 6: Stir and Add Milk
Once the pasta is tender:
Turn the slow cooker to LOW or WARM.
Gently stir the broccoli into the pasta.
Slowly pour in the milk, stirring as you go.
The mixture may look loose at first — this is normal and will thicken once the cheese melts.
Step 7: Add the Cheese
Add 1½ cups of shredded sharp cheddar cheese and stir until mostly melted and creamy.
Then:
Sprinkle the remaining ½ cup cheddar cheese on top.
Cover and let sit on LOW or WARM for 5–10 minutes until melted.
Step 8: Final Stir & Serve
Give everything one last gentle stir.
Taste and adjust seasoning with a pinch of salt and pepper if desired.
Serve warm straight from the slow cooker for a cozy, comforting meal.
Tips for Perfect Broccoli Cheddar Shells
Use freshly shredded cheese for smoother melting.
Cut broccoli into small florets for even cooking.
Check pasta early to prevent overcooking.
If pasta absorbs too much liquid, stir in a splash of warm milk.
Variations & Customization Ideas
Extra Creamy Version
Swap ½ cup of the milk for half-and-half for a richer sauce.
Milder Cheese Flavor
Add a small handful of shredded Colby Jack along with the cheddar.
Add Protein
Stir in:
A drained can of white beans
Chickpeas
Add them when you stir in the cheese so they warm through.
Crunchy Topping Option
For a baked-style finish:
Transfer the pasta to a baking dish.
Sprinkle with extra cheese and crushed butter crackers or breadcrumbs.
Broil for 2–3 minutes until golden and bubbly.
Feeding a Crowd?
Serve smaller portions alongside:
A fresh green salad
Garlic bread or breadsticks
Storage & Reheating
Refrigerator:
Store leftovers in an airtight container for up to 4 days.
Reheat:
Warm gently in the microwave or on the stovetop with a splash of milk to restore creaminess.
Freezer:
Freezing is not recommended, as dairy-based sauces may separate.
Frequently Asked Questions
Can I use frozen broccoli?
Yes, but thaw and drain it first to avoid excess water.
Can I cook this on LOW?
Cooking on LOW is not recommended for the initial stage. The pasta needs HIGH heat to cook properly in the broth.
What if my pasta is too soft?
Check early next time and switch to WARM as soon as shells are tender.
