Baked Cheddar Broccoli Noodle Casserole

Step 4: Make the Creamy Cheddar Sauce

In a large skillet or saucepan:

Melt the butter over medium heat.
Add the chopped onion and cook for 3–4 minutes until soft and translucent.
Stir in the garlic and cook for another 30 seconds.

Now build the sauce:
4. Sprinkle in the flour and stir continuously for about 1 minute to form a roux (this thickens the sauce).
5. Gradually pour in the milk, whisking constantly to avoid lumps.
6. Let the mixture simmer until it thickens slightly (about 3–5 minutes).

Once thickened:
7. Reduce heat to low and stir in the shredded cheddar cheese until melted and smooth.
8. Add sour cream, salt, pepper, and paprika. Mix until fully combined.

You should now have a rich, creamy cheese sauce.

Step 5: Combine Everything

In a large mixing bowl:

Add the cooked noodles
Add the broccoli
Pour in the cheese sauce

Gently fold everything together until evenly coated.

Step 6: Assemble the Casserole

Transfer the mixture into your prepared baking dish and spread it out evenly.

Step 7: Add the Topping

In a small bowl:

Mix breadcrumbs with melted butter and shredded cheese.

Sprinkle this mixture evenly over the casserole. This creates a crispy, golden crust that contrasts beautifully with the creamy interior.

Step 8: Bake

Place the casserole in the preheated oven and bake for 20–25 minutes, or until:

The top is golden brown
The edges are bubbling

If you want extra browning, you can broil for 1–2 minutes at the end—but watch closely to prevent burning.

Step 9: Rest and Serve

Remove from the oven and let it sit for 5–10 minutes before serving. This helps the casserole set and makes it easier to portion.

Serve warm as:

A main dish
Or a hearty side alongside roasted chicken or grilled meat

Tips for the Best Results

Use sharp cheddar: It gives a stronger, richer flavor compared to mild cheese.
Don’t skip the roux: It ensures a smooth, creamy sauce rather than a watery one.
Drain broccoli well: Excess water can thin out the sauce.
Customize it: Add cooked chicken, mushrooms, or even a pinch of chili flakes for variation.
