Ingredients You’ll Need
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
To make these flavorful seared ahi tuna steaks, you’ll need:
- 2 ahi tuna steaks (yellowfin tuna, about 4 oz each, 1 inch thick)
- 2 tablespoons soy sauce (preferably low-sodium)
- 1 tablespoon toasted sesame oil
- 1 tablespoon honey
- ½ teaspoon kosher salt (optional depending on sodium preference)
- ¼ teaspoon black pepper
- ¼ teaspoon cayenne pepper (optional for heat)
- 1 tablespoon cooking oil (canola, olive oil, or another high-heat oil)
- Green onions, toasted sesame seeds & lime wedges (optional for serving)
These simple ingredients work beautifully together without overpowering the delicate flavor of the tuna.
Let’s Get Started
1. Make the marinade
In a small bowl, whisk together soy sauce, sesame oil, honey, black pepper, and cayenne. Taste and adjust salt as needed — low-sodium soy may need a pinch more, while regular soy may need none.
2. Marinate the tuna
Place the tuna steaks in a shallow dish and pour the marinade over them. Coat on all sides.
Let the tuna sit for 10–15 minutes, flipping halfway through.
(You don’t want to marinate too long or the acid and salt will begin to cure the fish.)
3. Heat the skillet
Add 1 tablespoon of high-heat cooking oil to a cast-iron or heavy skillet.
Heat over medium-high until the oil shimmers — the pan needs to be hot to get that perfect sear.
4. Sear the tuna steaks
Place the tuna steaks into the hot pan.
Cook:
- 2 minutes on the first side
- 2 minutes on the second side
For a deeper crust, sear the edges for 20–30 seconds each.
This yields a beautifully rare center.
For medium, cook an additional 30–45 seconds per side.
Avoid cooking all the way through — tuna dries out quickly.
5. Rest and slice
Transfer the steaks to a cutting board and let rest for 2 minutes.
Slice against the grain into thin pieces.
6. Serve & enjoy
Plate the slices and garnish with:
- Green onions
- Toasted sesame seeds
- Lime wedges
The citrus brightens every bite.

Storage Tips
- Refrigerate: Store leftover tuna tightly wrapped for up to 2 days.

Ingredients
- Russet or Yukon Gold potatoes – thinly sliced for even baking
- Butter – for caramelizing the onions
- Yellow onions – the star of French onion flavor
- Garlic – adds depth and aroma
- Flour – helps thicken the creamy sauce

- Salt and pepper – essential seasoning
- Fresh thyme – optional but adds a fragrant touch
You may already have most of these ingredients in your kitchen!
Instructions
- Caramelize the onions
- Heat butter in a large skillet over medium-low heat. Add the thinly sliced onions and cook slowly, stirring occasionally, until they turn golden, soft, and sweet. This step may take 20–25 minutes — the deeper the caramelization, the richer the flavor. Add garlic during the last minute to avoid burning.
- Make the French onion cream sauce
- Sprinkle flour over the onions and stir to coat — this forms the thickening base. Gradually pour in beef broth while stirring, then add heavy cream. Simmer until the sauce becomes smooth, velvety, and slightly thickened. Season with salt, pepper, and fresh thyme.
- Slice the potatoes
- Using a mandoline or sharp knife, slice potatoes thinly and uniformly. Even slices help the dish cook evenly and keep the layers structured.
- Layer everything
- Grease a baking dish. Arrange a layer of sliced potatoes, spoon some of the French onion cream sauce over them, then sprinkle a generous amount of cheese. Repeat layers until all ingredients are used.
- Bake until bubbly
- Cover the dish with foil and bake at 375°F (190°C) for 45–50 minutes or until the potatoes are fork-tender. Remove the foil and bake an additional 15 minutes to brown the cheese and create a bubbly, golden top.
- Cool and serve
- Let the scalloped potatoes rest for 10 minutes before serving. This helps the sauce thicken and the layers stabilize.
Notes
- Low and slow equals flavor: The longer you caramelize the onions, the richer the dish becomes.
- Use Gruyère for best melt: Swiss works too, but Gruyère adds a classic nutty French flavor.
- Mandoline = perfect slices: Ensures even cooking and beautifully stacked layers.
- Add thyme sparingly: A little goes a long way — it enhances without overpowering.
- Make ahead option: Assemble the dish and refrigerate before baking; bake fresh when ready.
