Baked Vegetable Medley (2024)

This Baked Vegetable Medley Casserole is a quick and easy vegetable recipe with broccoli, cauliflower and carrots that is cheesy, creamy and crunchy.

Using California Blend mixed veggies and adding Swiss cheese, sour cream, cream of mushroom soup and French fried onions is a great way to add flavor to the vegetables at the dinner table.

Vegetable Medley Casserole Recipe

Starting with a couple bags of frozen California vegetable medley makes a colorful base for this baked vegetable side dish. A few simple ingredients are added to frozen cauliflower, broccoli and carrots to bring so much yummy flavor.

Of course the vegetables are the star of this dish, but I love how creamy it is and then the contrast of the crunchy French fried onions mixed in and sprinkled on top makes this recipe so enjoyable! I always get a big bag of fried onions so I can eat a few as I make this recipe!

Also called California Blend Casserole, this vegetable casserole recipe is easy enough to mix up for a weeknight meal but flavorful enough to serve at Thanksgiving, Christmas or Easter. We enjoy eating it with ham steak, BBQ Pulled Pork, or a chicken breast.

I’ve never been a vegetable lover, but this recipe, our and Zucchini Casserole with Stuffing all make eating veggies easier. My mom has always loved this baked Broccoli Mushroom Casserole as a personal favorite, but this vegetable medley is definitely my preferred way to bake veggies!

A few other classic holiday side dishes include our Scalloped Corn Casserole, Crock Pot Loaded Cauliflower Casserole and Bacon-Onion Green Beans. These are all warm vegetable dishes that taste super delicious!

I also love this Slow Cooker Creamed Corn my friend Mary shares for the holidays to go along with this vegetable casserole.

What Vegetables are in California Blend?

Broccoli, cauliflower and carrots are the vegetables in California Blend or California Medley.

This is a traditional mix of veggies that is still sold in many grocery stores. Modern packaging may just list the vegetables included and likely won’t reference California on the package.

Using a bag of frozen vegetables makes this recipe very convenient!

Ingredients Needed For California Vegetable Medley Casserole:

• Frozen California blend (broccoli, cauliflower and carrot mix)
• Cream of mushroom soup
• Swiss cheese
• Sour cream
• Pepper
• French fried onions

Tips for Making Frozen Vegetable Medley

• If any pieces of broccoli or cauliflower are too large carefully chop them into bite sized pieces
• Freshly shredded Swiss cheese maximizes flavors
• Recipe can be cut in half and baked in an 8″ or 9″ square baking dish
• Casserole tastes great reheated, but onions will be soft instead of crunchy as they absorb moisture in the refrigerator

Step By Step Instructions

Mix together the frozen veggies, cream of mushroom soup, Swiss cheese, sour cream and pepper. Also include half (3/4 cup) of the French fried onions.

Stir everything together well!

Pour into a lightly greased 9 x 13 inch baking dish.

Resist the urge to sprinkle the remaining onions on now. Let it bake for 30 minutes at 350°F.

Then sprinkle remaining onions on top and return to the oven until the onions are golden brown.

Serve warm and enjoy!
