Preparation

Step 1


To prepare the topping, boil the cauliflower in a medium-size pot until tender. Drain. Place the cooked cauliflower into the bowl of a food processor and pulse until puréed. Add the horseradish, yogurt, 1/2 cup Parmesan, salt, and white pepper. Purée again until smooth. Check for seasoning and adjust as necessary. Set aside while making the filling.


To prepare the filling, heat a 3-qt high-sided skillet on medium. Sauté the oil, onions, carrots, and celery until softened. Stir in the garlic, thyme, cooked ground beef, salt, and pepper. Once combined, put in the tomato paste, Worcestershire, and ketchup and sauté, scraping the mixture from the bottom of the skillet until it starts to darken. Add the flour and sauté briefly. Whisk in the beef stock until fully incorporated. Reduce to low heat and simmer until the mixture begins to thicken. Check for seasoning.


To assemble the pie, start by preheating the oven to 350°F. Pour the filling into a loaf pan, smoothing it out for even distribution. Spoon the cauliflower topping over the filling, and spread it out evenly with a spatula. Sprinkle with the remaining 1 Tbsp of Parmesan. Bake in the oven for 30 minutes, or until the top begins to brown slightly and the sides begin to bubble. Remove from the oven and let rest 5 minutes. Serve with crusty bread, if desired.
