Tips

Tip 1

Use leftover vegetables or steam fresh ones until tender before adding to keep texture firm after baking.

Tip 2

Reserve some cheese for topping to create an appealing golden crust that contrasts with the creamy interior.

Tip 3

Add milk gradually until mixture reaches desired consistency since prepared mac and cheese varies in thickness.

FAQ

Can I use frozen vegetables instead of fresh cooked ones?

Yes, thaw and drain frozen vegetables completely before mixing to prevent excess moisture from making the casserole watery.

What if I don't have colby-monterey jack cheese?

Any good melting cheese works well including cheddar, mozzarella, or a Mexican cheese blend for different flavor profiles.

How long will leftovers keep in the refrigerator?

Properly stored leftovers keep for 3-4 days refrigerated and reheat well in the microwave or low oven.
