Beef & Onion Deep Dish Pie

Beef and onion deep dish pie is the kind of one-dish dinner that makes a Tuesday feel like Sunday. Ground beef browned with onion and garlic gets bound with sour cream and a touch of flour, then crowned with puff pastry that bakes into a glossy, shattering top.

The sour cream is the smart move. It adds tang and richness without the long simmer that a classic stew filling needs, so this comes together in under an hour. A pinch of dried thyme and black pepper does the seasoning work, no need for a stocked spice cabinet.

Sweet peas add color and a quiet sweetness that cuts the richness of the meat. Folding them in last keeps them whole and bright instead of blown out and gray.

Pro Tips

• Drain the browned beef well before adding the sour cream. Excess fat splits the sauce into a greasy puddle instead of the silky binder you want.
• Cut the puff pastry to fit just inside the casserole rim, not over the edges. Pastry overhanging the dish slumps and tears as it puffs.
• Prick the pastry several times with a fork before baking. Without steam vents, the crust balloons and tears, then collapses unevenly.
• Brush the egg wash thinly. A heavy egg layer goes from golden to scorched in the last few minutes.

Variations

• Stir in 1 cup sliced cremini mushrooms with the onion for an earthier, beef bourguignon vibe.
• Swap ground beef for ground lamb and add a teaspoon of fresh chopped rosemary for a shepherd’s pie-meets-pot pie crossover.
• Top with shredded sharp cheddar between the filling and pastry for a melty layer.
