Ground wild boar simmered with mushrooms, wine, and aromatics in the Kana Goods Dutch oven until thick, spoonable, and cohesive, then wrapped in puff pastry and baked on their sheet pan for a crisp, even rise. Resting on their cooling rack keeps the base from steaming, preserving the layers you built.
Heat the olive oil in the Kana Goods Dutch oven over medium heat. Add the ground wild boar and cook until browned.
Stir in the minced onion, minced garlic, chopped celery, and roughly chopped cremini mushrooms. Sauté until softened and the mushrooms release their moisture.
Add the tomato paste and cook on low for 4 minutes, letting it caramelize and darken.
Deglaze with the white wine and reduce by half.
Add the beef stock, thyme, sea salt, and black pepper. Cook on low until the wild boar is tender and the mixture has thickened, about 1 hour.
Remove from heat, cool completely, then refrigerate until cold (overnight is ideal but not required).
Assemble & Bake (Kana Sheet Pan)
Preheat oven to 400°F (205°C).
Roll puff pastry slightly on a floured surface.
Spoon the chilled filling into the center, leaving a 1-inch border.
Fold and crimp edges to seal, or top with a second sheet and seal firmly.
Brush with egg wash.
Vent with a small cut.
Transfer to the Kana Goods Sheet Pan fitted with the Kana Cooling Rack.
Bake 25–30 minutes until puffed and golden brown
To Plate
Let the pie rest on the Kana Cooling Rack for 5 minutes so steam escapes.
Storage: cover and refrigerate for up to 3 days. Reheat in a 350°F oven until warmed through so the pastry stays crisp, microwaving will make it soggy.
