Why You’ll Love These Burgers
If you’ve ever pulled up to an In‑N‑Out drive‑thru and secretly wished the Animal‑Style magic could fit your keto macros, this recipe is your new weeknight hero. We’re taking my classic Easy Smash‑Style Keto Burgers and layering on a sugar‑free, low‑carb “animal style” dressing loaded with caramelized onions, garlic, and gooey cheddar.
Better yet, you can turn these into a Flying Dutchman copycat by swapping buns for my Crispy 2‑Ingredient Onion Rings – crispy cheese‑rimmed onion rings that hold up like mini buns!
Spoiler: each burger clocks in at under 5g net carbs.
Ingredient Line‑Up
For the Smash Burger Patties
- 1 lb 80/20 ground beef (makes 8 thin patties)
- Salt & pepper
- Avocado oil or ghee for the skillet
For the Animal‑Style Dressing
| Ingredient | Keto Perks |
|---|---|
| 2–3 yellow onions, diced | Natural sweetness without sugar |
| 2 cloves fresh garlic, minced | Depth of flavor; antimicrobial benefits |
| ¼ cup Walden Farms Thousand Island Dressing (0g sugar) | Classic sauce flavor, zero carbs |
| 1 oz shredded cheddar cheese | Melty, savory binder |
| 1 tbsp butter or ghee | Helps onions caramelize |
Optional Toppings & Swaps
- Dill pickle slices
- Leaf lettuce for a bun‑less option
- Sugar‑free ketchup + mustard swirl
- Swap cheddar for pepper jack if you like heat
Step‑by‑Step Instructions
1. Caramelize the Onions & Garlic
- Heat a skillet over medium‑high.
- Add 1 tbsp butter/ghee; once melted, toss in diced onions.
- Season lightly with salt; sauté 8–10 minutes, stirring often, until edges brown.
- Add minced garlic; cook 1 more minute.
- Stir in Walden Farms Thousand Island + 1 oz cheddar. Let cheese melt and sauce bubble. Remove from heat and keep warm.
Pro tip: The cheese thickens the sauce so it clings to the burger while delivering that signature gooey “animal style” vibe.
2. Smash Those Burgers
- Heat cast‑iron or heavy skillet over high until smoking.
- Divide ground beef into 4 loose balls (~4 oz each). Don’t over‑pack.
- Add a swirl of avocado oil. Place two balls in the skillet and smash immediately with a spatula or burger press until thin (¼ inch).
- Season with salt & pepper. Sear 2 minutes; flip, sear 1 minute more.
- Repeat with remaining patties.
3. Assemble & Serve
- Classic Keto Burger: Lay two patties on a lettuce wrap or keto bun, spoon a heaping tablespoon of animal‑style dressing over each, top with pickles, and dive in.
- Flying Dutchman Copycat: Sandwiched between two cheesy onion rings instead of a bun. Sauce in the middle = burger bliss.

Why Walden Farms Thousand Island?
Most Thousand Island dressings hide 4–5 g of sugar per tablespoon. Walden Farms uses sucralose, keeping this recipe sugar‑free without sacrificing that tangy, creamy profile. If you prefer a cleaner ingredient list, try Primal Kitchen Thousand Island (2 g net carbs). Adjust macros accordingly.
FAQ
Can I grill instead of pan‑searing?
Yes! Place a cast‑iron griddle on the grill grates; follow the same smash technique.
Are turkey burgers an option?
Absolutely. Use 93/7 ground turkey; expect slightly drier patties, so keep sauce generous.
What keto buns do you recommend?
- Hero Burger Buns (Aldi or Tom Thumb)
- Nature’s Own (what I used in this recipe – can get at Walmart)
- Oroweat
Or go bun‑free with lettuce or onion rings.
How do I keep smash patties from sticking?
Use high heat, pre‑oiled surface, and smash on parchment rounds for mess‑free removal.
