Kate’s Recipe Rundown
Is there anything that fried onions can’t improve? This Easy Broccoli Casserole has just 5 ingredients, and it’s topped with the always-delightful French’s fried onions.
I use the onions on my Easy Green Bean Casserole, too. They add the perfect amount of crunch to any casserole, and they definitely jazz up the broccoli here.
It’s a truly easy vegetable side dish that’ll be a hit with the family. And if you want a CHEESY version of this, try my Velveeta Broccoli Casserole next!
Enjoy! Kate

Tips and helpful hints
- Do not put the fried onions on top of the casserole until the last 5 minutes of baking time. Any onions on top will burn if they’re baked for too long.
- If you use frozen broccoli, make sure it is completely defrosted and drained before adding to the soup mixture.
- Buy a big can of fried onions so you have extra for snacking! 😉
Ingredients

- You can use fresh or frozen broccoli
- We’ll combine milk with cream of mushroom soup and soy sauce to create the sauce for the casserole. You can use any type of “cream of…” soup that you like, such as cream of broccoli, cream of chicken, cream of celery, etc.
- French’s crispy fried onions go both inside the casserole and on top.
How to Make Broccoli Casserole with Fried Onions
- Place broccoli in a large bowl, pour ¼ cup water in the bottom, cover, and microwave for 3–4 minutes, or until crisp tender. Drain the broccoli well.
- In a large bowl, whisk the cream of mushroom soup, soy sauce, and milk together.
- Pour the soup mixture over the cooked and drained broccoli, along with half of the friend onions. Stir gently to combine.
- Pour into an 8×8-inch pan, and bake for 25 minutes at 350°F. Top with the remaining fried onions and bake for an additional 5 minutes.

Variations
- Substitute cream of broccoli, cream of celery, or cream of chicken soup in place of the cream of mushroom soup.
- Add ½ cup of shredded cheese (like cheddar or Swiss) to the top, underneath the fried onions.
- Instead of fried onions, top the casserole with ½ cup crushed Ritz crackers mixed with 2 tablespoons of melted butter. Bake for 25 minutes total (the crumbs can be baked for the full 25 minutes without burning).

Broccoli Casserole with Fried Onions
This quick and easy Broccoli Casserole recipe has just 5 ingredients, with French's fried onions for the top!
Ingredients
- 1 lb fresh OR frozen broccoli
- 1 can (10.5 oz) condensed cream of mushroom soup (or cream of broccoli soup)
- ½ cup milk
- 1 teaspoon soy sauce
- 1½ cups French’s fried onions divided
Instructions
- Preheat oven to 350°F. Grease an 8×8 inch baking dish.
- Cut the broccoli into small florets. Place in a large microwavable bowl, and pour ¼ cup water into the bottom of the bowl. Cover and microwave for 4 minutes, or until the broccoli is just tender. Drain the broccoli well.
- In a medium bowl, whisk together the condensed cream of mushroom soup, milk, soy sauce.
- Add the soup mixture to the drained broccoli, along with ½ cup of the onions. Mix to combine.
- Pour into the prepared baking dish. Cover with foil and bake for 20 minutes. Top with the remaining fried onions and bake for another 5 minutes. Serve while warm.
Notes
Do not reconstitute the condensed soup—just pour the can into the bowl as-is.
You can use cream of broccoli soup, cream of celery soup, or cream of chicken soup in place of the cream of mushroom soup.
After steaming frozen broccoli, make sure it is completely defrosted. Microwave for 1–2 minutes longer if needed, to remove all of the ice crystals.
You can also use a steamer basket to steam the broccoli. Pour 1 inch of water in a large saucepan. Add a steamer basket and broccoli. Bring the water to a boil, then cover and steam for 4 minutes.
Make it ahead: assemble the casserole as directed but do not bake it, and do not add the fried onions on top. Cover and refrigerate for up to 1 day. Bake as directed when you’re ready to serve it.
Reheating instructions: cover the casserole with foil, and place in a 350°F oven for 10–15 minutes, or until warmed through. If you want the onions on top to be crisp, add additional fried onions to the top, and bake for 2–3 minutes more.
