About these measurements

Metric is the default. US cups are 236.588 mL, not 250 mL. Flour, sugar and other supported dry ingredients use ingredient-specific weight conversions; they are not treated as water. Displayed conversions are rounded.

Where a reliable weight-to-volume conversion is unavailable, weighed ingredients use ounces or pounds in the US view; spoon-measured ingredients use millilitres in the metric view. Ounces (oz) mean weight, not fluid ounces. Counts, pinches, and “to taste” remain unchanged.

For baking and very small quantities, a kitchen scale is more reliable than estimated cups. Changing units does not adjust the recipe for a fan oven or a different pan.

Step-by-Step Cooking Instructions

1. Prep the Aromatics

Peel one large onion and 6 cloves of garlic.
Drop the onion and garlic cloves directly into a food processor and pulse until they are cleanly chopped down into fine bits.

2. Sauté and Deglaze

Set your cooking pot over high heat.
Add 59 mL of olive oil to the bottom of the pot.
Dump in the processed garlic and onions, stirring continuously to let them sweat and cook down.
Pour 118 mL of vodka directly over the hot garlic and onions. Stir gently and allow the liquid to cook down to bring out the natural sweetness of the aromatics.

3. Brown and Season the Beef

Add your 1 kg of ground beef into the pan with the sweet onions and garlic.
Shake in your first heavy layer of seasonings: add a balanced amount of onion powder, Creole seasoning, Slap Ya Mama, thyme, white pepper, rosemary, and salt.
Stir well to break up the meat as it browns.
Taste the meat as it cooks and repeat with a duplicate layer of seasonings if it requires more flavor depth.
Juiciness Pro-Tip: To ensure your meat base stays exceptionally moist, slightly undercook the beef so there are still a few pink bits remaining. Because the dish finishes in the oven, the meat will cook through perfectly later without drying out. Spoon in a small splash of leftover chicken broth if you prefer an even juicier meat sauce.
Transfer the finished beef mixture into a separate bowl and set it aside.

4. Cook the Potatoes

Peel and chop your 2 kg of potatoes into uniform chunks.
Place the potatoes directly into a cooking vessel and submerge them completely in chicken stock instead of plain water.
Cook the potatoes until they are completely tender.
Strain the cooked potatoes out of the liquid using a slotted spoon, allowing a tiny splash of the starchy chicken stock to remain behind for flavor. Note: Avoid letting too much boiling liquid stay with the potatoes, as excess water will cause your mash to turn gritty and runny.

5. Mash and Build the Goat Cheese Potatoes

Transfer the hot potatoes to a mixing bowl and drop in 300 g of goat cheese, 113 g of butter, and pour over the heavy cream.
Mash the ingredients together aggressively. The residual heat from the hot starches will naturally melt the cheese and butter into a thick, velvety consistency.
Taste for seasoning and spice up the mash by folding in garlic powder, salt, onion powder, black pepper, and a light touch of rosemary and thyme. Stir until the cheese completely dissolves and the mixture is totally smooth.

6. Assemble the Casserole

Grab a standard deep baking dish.
Spread your seasoned, juicy ground beef mixture evenly across the absolute bottom of the dish to form the first solid layer.
Spoon the rich goat cheese mashed potatoes directly over the beef. Use a spatula to carefully smooth the potatoes out to the perimeters of the dish, locking the meat beneath it.
Scatter 200 g of shredded Emmental cheese generously across the entire top surface of the potatoes to ensure full coverage.

7. Bake, Garnish, and Serve

Preheat your oven to 175 °C.
Place the uncovered baking dish onto the center rack of your oven.
Bake until the casserole is bubbling hot and the Emmental cheese transforms into a beautiful, crispy, golden-brown crunchy topping.
Carefully remove the hot dish from the oven.
Scatter your 20 g of chopped fresh chives evenly across the molten cheese crown for a vibrant pop of color and freshness. Slice into thick squares and serve hot.
