- Salt and pepper, to taste: Basic seasoning that lets the beef do its thing.
Sauce & Flavoring

How to Make French Onion Beef Casserole (Step-by-Step)
Ready to jump in? This French Onion Beef dish is so simple, you’ll wonder why it’s not already a weekly thing. Let’s do this.
Step 1: Prep Your Oven and Pan
Start by heating your oven to 350°F. Grab a 9×13-inch baking pan and hit it with some non-stick spray. It’s a small move, but it saves you from scrubbing later—and who’s got time for that? Keeps everything sliding out easy when it’s done.
Pro Tip: No spray? A quick swipe of butter or oil does the trick—just don’t go overboard.
Step 2: Cook the Noodles
Get a big pot of water going—add a pinch of salt and bring it to a boil. Toss in your 10 ounces of egg noodles and cook them per the package, usually 7-9 minutes. Stir them a bit so they don’t stick together. Drain them well when they’re done. You want them soft but not falling apart—they’ll soak up more goodness later.
Pro Tip: After draining, rinse with cold water to stop the cooking. Keeps them firm for the casserole.
Step 3: Brown the Beef
While the noodles boil, heat a large skillet over medium-high. Add your 1 pound of lean ground beef and break it up with a spoon as it cooks. Let it go until there’s no pink left—about 5-7 minutes. Sprinkle in salt and pepper to taste. Drain any grease once it’s done. Greasy casseroles? Hard pass.
Pro Tip: Toss in a pinch of garlic powder with the seasoning for a little extra oomph—works every time.
Step 4: Mix the Sauce
With the beef still in the skillet, stir in both cans of cream of mushroom soup and the 15 oz jar of Lay’s French Onion Dip. Mix it until it’s all smooth and creamy. The smell alone will make you hungry—it’s that good. Gently fold in your cooked noodles. Don’t smash them; just let them mingle with the sauce.
Pro Tip: If it’s too thick, add a splash of milk—a tablespoon or two loosens it right up.
Step 5: Assemble and Top
Pour that beefy, noodle mix into your prepped 9×13 pan. Spread it out so every scoop’s perfect. Then, scatter the ½ cup of French’s fried onions over the top. Don’t skimp here—it’s the crispy crown that seals the deal. Looks good already, right?
Pro Tip: For extra crunch, sprinkle a few more onions halfway through baking—total game-changer.
Step 6: Bake and Enjoy
Slide the pan into your 350°F oven, uncovered, and bake for 20 minutes. You’re just warming it through and crisping those onions. Pull it out when it’s hot and bubbly—let it sit a sec before digging in. Serve it warm, and watch it disappear.
Pro Tip: Got a broiler? Hit it for 1-2 minutes at the end for an extra crispy top—just don’t walk away.
Tips for Success
Want to ace this French Onion Casserole? Here’s what I’ve figured out:
- Cook the noodles just shy of done—they’ll finish in the oven.

- Mix in some shredded cheddar before baking for a richer vibe.
- If the top browns too quick, loosely cover with foil for the last bit.
