Baked French Onion Beef Casserole with crispy onions on top in a casserole dish

Ingredients

10 ounces dried egg noodles
1 pound lean ground beef
2 cans (10.75 ounces each) condensed cream of mushroom soup
1 (15-ounce) jar Lay’s French Onion Dip
1 cup French’s fried onions

Step-by-Step

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to prevent sticking.
Bring a large pot of salted water to a boil. Cook the egg noodles according to package directions until just al dente. Drain and set aside.
In a large skillet over medium heat, brown the ground beef until fully cooked, breaking it up with a spoon as it cooks. Drain off any excess grease for a lighter casserole.
Reduce the heat to low, then stir in both cans of condensed cream of mushroom soup and the full jar of French onion dip. Mix well to combine everything into a thick, creamy sauce.
Add the drained noodles to the beef and sauce mixture, stirring gently to ensure all noodles are coated evenly.
Transfer the mixture to your prepared baking dish, spreading it into an even layer.
Sprinkle the cup of French’s fried onions evenly over the top for an irresistible crispy crust.
Bake uncovered for 25-30 minutes, or until the casserole is bubbly and the onions are golden brown.
Let rest for 5 minutes before serving.

What to Serve French Onion Beef Casserole With

Looking to build out your meal? Serve your French Onion Beef Casserole alongside a simple green salad tossed in a light vinaigrette to balance the richness. Roasted veggies like broccoli or green beans pair perfectly, soaking up the savory sauce. For a comfort-food feast, add warm dinner rolls or a crusty baguette—perfect for mopping up every last drop. If you’re serving guests, a glass of dry red wine complements the flavors beautifully. Don’t forget a tangy pickle or sharp coleslaw for something fresh and crunchy!

Top Tips for Perfecting French Onion Beef Casserole

For a lighter version, substitute ground turkey for beef or use low-fat cream of mushroom soup.
Can’t find Lay’s French Onion Dip? Swap in any creamy French onion dip, or make your own with sour cream and dry onion soup mix.
To avoid soggy noodles, don’t overcook them before baking—al dente is ideal since they’ll continue cooking in the oven.
Craving more cheese? Add shredded Swiss or gruyere to the casserole before topping with onions.
If making ahead, assemble everything except the fried onions. Store covered in the fridge, then add onions and bake when ready.

Storing and Reheating Tips

French Onion Beef Casserole makes fantastic leftovers! Allow the casserole to cool completely before covering tightly with foil or transferring to an airtight container. Store in the refrigerator for up to 3 days. To freeze, cover the cooled casserole tightly with both plastic wrap and foil (leave off the fried onions if preparing ahead), and freeze for up to 2 months.

To reheat, thaw overnight in the fridge if frozen. Bake, covered with foil, in a 350°F oven for 20-30 minutes, until heated through. Add a fresh sprinkle of fried onions in the final 5 minutes to maintain crunch. For single servings, reheat in the microwave, stirring halfway for even warming.

FAQs

1. Can I make this casserole ahead of time?
Yes! Assemble the casserole up to the point of adding fried onions and refrigerate. When ready to bake, add onions and cook as directed.

2. Can I use a different type of noodle?
Absolutely! Rotini, penne, or even spaghetti will work if you don’t have egg noodles.

3. What can I substitute for cream of mushroom soup?
Cream of chicken or celery soup work well, or use a homemade white sauce if you prefer.

4. Is this recipe freezer-friendly?
Yes, but for best texture, add the fried onion topping after reheating rather than before freezing.

5. Can I add veggies to the casserole?
Definitely! Mushrooms, spinach, or peas can be sautéed and stirred in with the beef for extra nutrition.
