This casserole brings together tender California vegetables and creamy cheddar cheese for a comforting slow cooker dish that’s both easy and satisfying.

I started making this during a busy week and it quickly became a favorite comfort food at home. It’s the kind of dish that feels like a warm hug on a plate.

Ingredients

  • Cheddar cheese: shredded to melt beautifully and add rich creaminess. Use a good quality sharp cheddar for the best flavor
  • Vegetable broth: to keep the casserole moist and enhance the veggie taste
  • Condensed cheddar cheese soup: brings extra cheesy depth and creaminess without extra effort
  • Frozen California vegetable mix: of broccoli cauliflower and carrots provides a colorful variety and tender texture. Choose fresh frozen bags for optimal quality

Step-by-Step Instructions

Spoon the Mix into the Slow Cooker:
Add the frozen vegetables the condensed cheddar cheese soup half the shredded cheddar and vegetable broth to your slow cooker. Stir everything well so the flavors combine evenly
Set and Forget on Low Heat:
Place the lid on and cook on low for three to four hours until the vegetables are just tender but not mushy
Top with Extra Cheese:
Sprinkle the remaining shredded cheddar cheese evenly over the top of the vegetables then cover again

I always keep extra shredded cheddar on hand because that melty cheesy topping makes all the difference. It reminds me of cozy family dinners where everyone asks for seconds.
