Ingredients (~6 servings)

  • 1 bag (16 oz) frozen California medley vegetables
  • 1 can (10.5 oz) cheddar cheese condensed soup
  • 3 Tbsp milk
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/4 tsp ground black pepper
  • 1 1/2 cups shredded cheddar cheese (divided)
  • 3 oz crispy fried onions

 

Prep Your Oven and Baking Dish

Preheat the oven to 425F and grab a 9″ x 13″ baking dish.

Spray it with cooking spray – this prevents the cheese from sticking to the bottom.

Blanch the Frozen Vegetables

Bring a large pot of salted water to a rolling boil and add the frozen vegetable mixture.

Boil just until the vegetables are warmed through – this takes ~2-3 minutes.

The vegetables should still have some bite to them; you’re not cooking them fully since they’ll finish in the oven.

Drain in a strainer and set aside.

Make the Cheese Sauce Base

In a large bowl, combine the cheddar cheese soup, milk, garlic powder, onion powder, and black pepper.

Stir until well combined and smooth.

Add 1 cup of the shredded cheddar cheese to the soup mixture and stir just until combined.

The cheese will melt more in the oven, so don’t worry if it’s not perfectly smooth right now.

Combine Vegetables with Sauce

Add the drained vegetables to the cheese mixture and fold them in gently.

Make sure all the vegetables are completely coated with the sauce.

Pour everything into your prepared baking dish and top with the remaining 1/2 cup of shredded cheddar cheese.

Bake Until Bubbly

Bake for ~20-25 minutes, until heated through and bubbly around the edges.

You’ll see the cheese on top start to brown slightly and the sauce will be bubbling.

Remove from the oven and sprinkle the crispy fried onions evenly on top.

Bake for an additional 5 minutes to crisp the onions, or broil for ~1-2 minutes if your baking dish is broil-safe.

The onions should be golden and crunchy.

Remove from the oven and allow to cool for ~5 minutes before serving – the cheese sauce will be molten hot.
