Texas Roadhouse Roadkill Recipe (Easy Copycat)

Texas Roadhouse’s Roadkill is one of those menu items that sounds chaotic but delivers in the best way — a smashed hamburger patty topped with sautéed mushrooms and onions, all piled on a bed of seasoned mashed potatoes and smothered in brown gravy. If you want that same dinner at home without the wait, this recipe gets you there in about 45 minutes.

It’s a genuinely filling plate of food. The kind you make on a weeknight when everyone is hungry and you want something that feels like more than just dinner.

Why I Love This Recipe

This is the version I keep coming back to when I want something hearty without a lot of fuss. The smashed patty gets crispy edges from the cast iron, and the mushroom and onion topping adds a savory, slightly sweet layer that pairs well with the salty gravy.

The mashed potatoes are the backbone here. Butter and sour cream keep them rich and smooth, and they soak up the gravy in a way that makes the whole plate come together.

Recipe Ingredients

• 1.5 lbs ground beef (80/20) – The fat content gives you better browning and juicy patties; lean beef will dry out
• 1 tsp garlic powder – Goes into the patty seasoning
• 1 tsp onion powder – Rounds out the beef flavor
• 1 tsp kosher salt – For the patties; adjust to taste
• 0.5 tsp black pepper – Freshly cracked if you have it
• 1 tbsp vegetable oil – For searing the patties
• 8 oz cremini mushrooms, sliced – Button mushrooms work too
• 1 large yellow onion, thinly sliced – About 2 cups sliced
• 2 tbsp unsalted butter – For cooking the mushrooms and onions
• 2 cups beef broth – Base for the brown gravy
• 2 tbsp all-purpose flour – Thickens the gravy
• 1 tbsp Worcestershire sauce – Adds depth to the gravy
• 2 lbs Yukon Gold potatoes, peeled and cubed – Yukon Golds are naturally creamy and don’t need much help
• 4 tbsp unsalted butter (for potatoes) – Keep it separate from the 2 tbsp used for the topping
• 0.5 cup sour cream – Keeps the mash rich and slightly tangy
• 0.25 cup whole milk, warmed – Add more if you prefer a looser mash
• 1 tsp kosher salt (for potatoes) – Season the mash separately
• 2 tbsp fresh chives, chopped – Garnish for the finished plate

Variations / Substitutions

• Ground turkey instead of beef – The patties will be leaner and slightly less crispy on the edges; bump the seasoning a little to compensate.
• Portobello mushrooms instead of cremini – Chunkier texture and a meatier bite; slice them thick so they don’t disappear into the sauce.
• Chicken broth instead of beef broth – The gravy will be lighter in color and a bit milder, but it still works.
• Dairy-free swap – Use olive oil instead of butter, oat milk instead of whole milk, and a plain unsweetened coconut yogurt instead of sour cream in the potatoes; the texture will be slightly less silky but still good.
• Add heat – Stir 0.5 tsp crushed red pepper flakes into the gravy at the end for a gentle kick.
• Smoked paprika in the patty – Swap the garlic powder for 1 tsp smoked paprika for a slightly smoky, barbecue-adjacent flavor.

How To Make Roadkill

Step 1: Boil the Potatoes

Put the 2 lbs of peeled and cubed Yukon Gold potatoes in a large pot and cover them with cold salted water. Bring to a boil over high heat, then reduce to a steady simmer and cook for 15 to 18 minutes, until a fork slides in without any resistance.

While the potatoes cook, you have plenty of time to get the rest of the dish moving. Don’t rush the boil — undercooked potatoes make lumpy mash no matter how much you work them.

Step 2: Sear the Patties

While the potatoes are simmering, mix the 1.5 lbs ground beef with the 1 tsp garlic powder, 1 tsp onion powder, 1 tsp kosher salt, and 0.5 tsp black pepper in a bowl. Divide the mixture into 4 equal portions and press each one into a thin, flat patty, about 0.5 inch thick.

Heat the 1 tbsp vegetable oil in a large cast iron skillet over medium-high heat until it just starts to shimmer, about 1 minute. Add the patties and press them down firmly with a spatula. Cook for 3 to 4 minutes per side until you get a deep brown crust on both sides. Set them aside on a plate; they’ll finish warming through under the gravy later.

The crust is the point here. If the pan isn’t hot enough before the meat goes in, you’ll get gray patties instead of the brown, crispy edges that make this dish worth making.

Step 3: Sauté the Mushrooms and Onions

Without washing the skillet, reduce the heat to medium and add the 2 tbsp unsalted butter. Once it foams and settles, add the 8 oz sliced cremini mushrooms and the thinly sliced large yellow onion. Cook, stirring occasionally, for 10 to 12 minutes until the onions are soft and golden and the mushrooms have released their moisture and started to brown.

Don’t stir constantly — the mushrooms need contact with the pan to actually brown rather than steam. You want the onions limp and caramelized at the edges, not just softened.

Step 4: Build the Gravy

Scatter the 2 tbsp all-purpose flour over the mushroom and onion mixture and stir for about 1 minute to cook out the raw flour taste. Pour in the 2 cups beef broth and the 1 tbsp Worcestershire sauce, scraping up any browned bits from the bottom of the pan.

Bring to a simmer and cook for 4 to 5 minutes, stirring occasionally, until the gravy thickens enough to coat the back of a spoon. Nestle the seared patties back into the skillet, pressing them down slightly, and let everything simmer together for 2 more minutes so the flavors come together.

The gravy should be savory, glossy, and just thick enough to hold its shape when you spoon it. If it looks too thin at 5 minutes, give it another minute or two; if it thickens too much, splash in a bit of water.

Step 5: Mash the Potatoes

Drain the cooked potatoes and return them to the warm pot over low heat for about 1 minute to let any remaining moisture evaporate. Add the 4 tbsp unsalted butter and mash until the butter is fully absorbed, then stir in the 0.5 cup sour cream, 0.25 cup warmed whole milk, and 1 tsp kosher salt.

Mash to your preferred texture. A few small lumps are fine — this is a rustic plate of food, not a fine dining side dish. Taste and adjust salt before plating.

Step 6: Plate and Garnish

Spoon a generous mound of mashed potatoes into the center of each plate. Lay a seared patty on top, then ladle mushrooms, onions, and plenty of the brown gravy over everything. Finish with a scatter of the 2 tbsp chopped fresh chives across the top.

Recipe Tips

• Choose 80/20 ground beef. The extra fat is what gives you those crispy, browned edges on the patty. Leaner beef won’t brown the same way at this heat.
• Don’t crowd the potatoes. If your pot is small, boil them in 2 batches. Crowded potatoes cook unevenly and you’ll end up mashing some pieces that are still slightly firm in the middle.
• Warm your milk before adding it to the mash. Cold milk can make the potatoes gluey. Thirty seconds in the microwave is all it takes.
• Make the gravy last if timing is tricky. The mash holds well with a lid on over very low heat. The gravy reheats quickly, so you can finish that while the mash stays warm.

Bake times don’t apply here, but here’s a quick guide to scaling the mash if you’re feeding a crowd or cooking for 2:

Servings	Potatoes	Butter	Sour Cream	Milk
2	1 lb	2 tbsp	0.25 cup	2 tbsp
4 (standard)	2 lbs	4 tbsp	0.5 cup	0.25 cup
8	4 lbs	8 tbsp	1 cup	0.5 cup

How To Store

• Refrigerate – Store leftover patties, gravy, and mash separately in airtight containers for up to 3 days. The gravy tends to thicken overnight; that’s normal.
• Reheating – Reheat the mash in a saucepan over low heat with a splash of milk to loosen it back up. Warm the gravy and patties together in a skillet over medium-low heat for about 5 minutes.

What To Serve With Roadkill

A crisp green salad with a sharp vinaigrette cuts through the richness of the gravy nicely — the acid keeps the meal from feeling too heavy. Steamed broccoli or roasted green beans work well alongside it for the same reason; something with a little bitterness or brightness balances the savory, buttery plate. Texas Roadhouse-style dinner rolls are the natural companion if you want to round it out the way the restaurant does, since they’re soft enough to soak up any extra gravy on the plate.

Frequently Asked Questions

Can I make the gravy ahead of time?

Yes. Make it up to 2 days ahead and refrigerate it. Reheat it over medium-low heat and whisk in a splash of broth if it has thickened too much.

Can I use frozen hamburger patties instead of making my own?

You can, but the smashed-and-seared technique is harder to pull off with a pre-formed frozen patty. If you use frozen ones, thaw them fully first and press them thinner before they hit the pan.

What if my gravy turns out lumpy?

Whisk it vigorously over medium heat for 1 to 2 minutes. Lumps usually come from flour that wasn’t stirred in evenly before the broth was added; a good whisk almost always smooths them out.

Can I make this dish gluten-free?

Yes. Swap the 2 tbsp all-purpose flour for 1 tbsp cornstarch mixed with 2 tbsp cold water, and stir that slurry into the broth instead. The gravy will be slightly glossier but just as thick.
