Ingredients
For the burgers:
- 1 lb ground beef (80/20 for the juiciest patties)
- Salt & pepper
- 4–6 slices Swiss cheese
- 4 brioche buns, toasted
- BBQ sauce (any flavor you love — sweet, smoky, or spicy)
- 1–1 ½ cups French’s Crispy Fried Onions
- Bacon slices (optional, but fantastic)
- Pickles (optional)

How to Make Cowboy Smashed Burgers
1. Form loose meat balls
Keep them loose — don’t pack tightly. This helps create those signature crispy edges when you smash them.
2. Smash on a hot griddle or cast-iron skillet
Drop on your meat ball and immediately press down using a spatula or burger press.
Season with salt and pepper.
3. Let the crust develop
Don’t move them! After 2 minutes, the edges will get lacy, golden, and crispy.
4. Add the Swiss cheese
Top each patty and let it melt right into all those ridges.
5. Toast your brioche buns
A quick toast in butter or on the hot griddle makes them soft, warm, and lightly golden.
6. Build your cowboy burger
Here’s my favorite way to stack it:
Bottom bun → BBQ sauce → cheesy smashed patty → bacon → a big handful of French’s crispy onions → more BBQ sauce → top bun.
The crunch is unreal.

Helpful Tips
- Add the onions right before serving so they stay crispy.
- Use parchment paper when smashing to prevent sticking.
- Don’t flip too soon — let the crust form.
- Try a smoky BBQ sauce for the most cowboy-style flavor.
Variations You Can Try
- Spicy Cowboy: Add some pickled jalapeños.
- Cowboy Ranch: Mix ranch with BBQ sauce for a creamy drizzle.
- Double Cowboy: Make two smashed patties and layer them with extra Swiss.
- Garlic Cowboy: Brush the brioche buns with garlic butter before toasting.
What to Serve With These Burgers
- French fries
- Onion rings
- Potato wedges
- Corn on the cob
- Macaroni salad
- A cold ranch chopped salad
This burger plays well with any classic cookout side.

Frequently Asked Questions
Can I use a different cheese?
Yes! Cheddar, pepper jack, white American, or gouda all work. But Swiss melts like a dream for this recipe.
Do I have to use a flat top?
Nope — cast iron works perfectly. Just get it very hot.
Will the French’s onions stay crispy?
They stay perfectly crunchy if you add them right before eating.
