Method
Step 1: Prepare the Mashed Potatoes
- Start by bringing a large pot of salted water to a boil. Once boiling, add your cubed potatoes. They'll need about 15 to 20 minutes of cooking until tender. You want them soft enough to mash effortlessly. Once done, drain the potatoes and return them to the pot. Add the butter, milk, sour cream, and heavy cream. Mash everything together. A potato ricer works wonders here if you're after an ultra-smooth texture. Season with salt and pepper to taste, then fold in the Parmigiano Reggiano. Set the mashed potatoes aside.
Step 2: Cook the Filling
- In a large skillet over medium heat, add the chopped pancetta. Cook until it’s crispy, letting its flavor infuse the fat. Next, add the onion, carrot, and celery. Sauté for about 5 minutes until they soften. Now, add the mushrooms and garlic. Stir them in and cook until the mushrooms have released their moisture. This is where it starts to smell divine.
Step 3: Add the Meat and Flavor
- Toss in the ground lamb (or beef, if that’s your jam). Cook until browned, breaking it up as it cooks. It should take about 8 minutes. Next, stir in tomato paste, Worcestershire sauce, rosemary, thyme, and paprika. Now it’s time for the red wine. Pour it in and let it cook down for a few minutes to concentrate the flavor. Add the beef stock and let the mixture simmer for about 10 minutes until thickened. Toss in the peas and mix.
Step 4: Assemble the Dish
- In a large baking dish, spread the meat and veggie mixture evenly across the bottom. Spoon your mashed potatoes generously over the top. I love using a fork to create little peaks in the potatoes. They’ll get crispy in the oven!
Step 5: Bake
- Preheat your oven to 400°F (200°C). Bake for about 25 to 30 minutes or until the mashed potatoes are beautifully golden on top.
Step 6: Let it Rest
- Once out of the oven, allow the dish to rest for about 10 minutes before serving. This will help all the flavors meld together beautifully.
Notes
- Use starchy potatoes for creamy mashed potatoes; russets work great.
- Taste as you go! This will allow you to adjust seasonings according to preference.
- Feel free to mix meats. A blend of beef and pork could add more flavor.
- Leftover veggies can shine! Toss in any vegetables you need to use up.
- Make-ahead friendly: You can prepare this a day in advance and bake before serving.
