Braised Short Rib Pot Pie with French Onion

If you love French onion soup, this French Onion Short Rib Pot Pie belongs on your weekend menu. Deeply caramelized onions are combined with slow-braised short ribs for a melt-in-your-mouth filling, finished with a blanket of melted Gruyère cheese and enclosed in flaky, golden puff pastry. The flavors are rich and layered, yet the steps are straightforward: braise the short ribs, caramelize the onions, combine them into a savory filling, then assemble and bake the pot pie. Every bite delivers comforting, restaurant-quality flavor.

Bring the flavor of a French bistro to your kitchen

The first time I tasted the filling I nearly ate the entire pot with a fork. The combination of tender, slow-braised short ribs and intensely caramelized onions is addictive. It’s one of those recipes that surprises you with how deeply satisfying simple ingredients can become when given time and attention.

After many years of recipe testing, I still love when a new idea knocks my socks off. This pot pie is exactly that: familiar comfort—think French onion soup and braised short ribs—reimagined inside a flaky puff pastry. I’ve made a full-size pot pie for family dinners and smaller, individual versions for parties; both formats work beautifully.

To save time, prepare the filling a day or two ahead. The flavors improve after a short rest, and assembling and baking the pot pie takes less than an hour when the filling is ready. Complex flavor, simple technique—this recipe is a great weekend project that yields a truly impressive result.

Key ingredients

Below are the essential ingredients and a few notes to help you shop and prepare. For exact measurements, see the recipe section further down.

  • Beef short ribs – Choose beef chuck short ribs (often labeled “English-style”). Bone-in short ribs offer the best flavor and texture after braising, but boneless work if that’s what you can find.
  • Steak seasoning – A simple blend of kosher salt, coarse black pepper, dried minced onion, and garlic works well. A coarse steak seasoning enhances the crust when you sear the ribs.
  • Puff pastry – Use frozen puff pastry sheets from the grocery store (two per package). Thaw the sheets before assembling; they roll out more easily and bake to a crisp, flaky crust.
  • Gruyère cheese – Shredded Gruyère melts into a rich, nutty layer that complements the onion-and-beef filling.

Instructions overview

This recipe is divided into three main components: braising the short ribs, caramelizing the onions and making the filling, and assembling and baking the pot pie. Read through each section before you begin so the timing lines up—onions should caramelize while the ribs braise.

Start by preparing the braised short ribs

Caramelize the onions on the stove while the short ribs braise

Dice the onions and cook them slowly until they are deeply caramelized—this takes about 90 minutes. When the ribs are finished braising, remove the meat from the bones and shred it. Strain the braising liquid through a fine-mesh strainer and reserve 2 cups of the strained beef broth to use in the pot pie filling.

Once the filling is ready, let it cool. The filling can be made up to four days ahead and stored refrigerated, or frozen for longer storage.

How to make mini pot pies

Turn this pot pie into an irresistible party appetizer by making mini versions in a muffin tin. Cut 5-inch circles from puff pastry, press them into the tin, par-bake, then fill with about 3 tablespoons of the cooled filling and a sprinkle of Gruyère. Finish baking until the cheese is melted and the pastry is golden. With the filling this recipe yields, you can make roughly 28 mini pies using three sheets of puff pastry.

Make-ahead and freezer tips

You can make the filling ahead and keep it in the refrigerator for up to five days. For longer storage, cool completely and freeze in a freezer-safe container for up to six months. Thaw overnight in the refrigerator before assembling the pot pie.

Avoid assembling the pot pie with unfrozen or partially thawed puff pastry; the pastry must be fully thawed and handled gently to ensure it bakes into crisp, flaky layers. If you like, make a double batch of filling: assemble one pot pie now and freeze the other portion for an easy future meal.

Ingredients

Short Ribs

  • 4 pounds bone-in beef chuck short ribs (or 3 pounds boneless)
  • 4 tablespoons steak seasoning
  • 2 tablespoons olive oil
  • 4 cups beef broth
  • 2 tablespoons Worcestershire sauce
  • 2 bay leaves
  • 2 sprigs fresh thyme (or 1 teaspoon dried)

Caramelized Onions

  • 3 tablespoons unsalted butter
  • 3 pounds onions, diced into 1/4-inch pieces
  • 1/2 teaspoon sea salt

Pot Pie & Filling

  • 3 cloves garlic, minced
  • 2 cups beef broth (reserved from the short ribs)
  • 1/4 cup all-purpose flour
  • 2 sheets puff pastry dough, thawed
  • 1 1/2 cups Gruyère cheese, shredded
  • 1 egg (for egg wash)

Instructions

Short Ribs

  1. Preheat the oven to 350°F (175°C).
  2. Rub the short ribs all over with the steak seasoning.
  3. Heat the olive oil in a large dutch oven over medium-high heat. Sear the short ribs on all sides until browned.
  4. Pour in the beef broth and scrape up any browned bits from the pan. Add Worcestershire sauce, bay leaves, and thyme. Cover and transfer to the oven. Braise for about 3 hours, until the meat is very tender.
  5. Remove the pot from the oven. Take the short ribs out of the braising liquid and shred the meat using two forks. Strain the remaining liquid through a fine-mesh strainer, discard solids, and measure out 2 cups of the strained broth for the filling.

Caramelized Onions and Filling

  1. About 1 1/2 hours into the ribs braising, melt the butter in a large pot or dutch oven over medium-high heat. Add the diced onions and spread them evenly in the pan.
  2. Cook for 5 minutes, sprinkle with salt, then reduce heat to medium. Cook the onions for about 90 minutes, stirring every 15 minutes until deeply caramelized.
  3. Stir in the minced garlic and cook one minute. Add 1/4 cup of the reserved beef broth to deglaze the pot, scraping any browned bits from the bottom.
  4. Sprinkle the flour evenly over the onions, stir, and cook for one minute. Add the remaining 1 3/4 cups of reserved beef broth and the shredded short ribs. Bring to a boil over high heat, then simmer until most of the liquid has cooked away, about 5–7 minutes. Remove from heat and let cool.

Assemble and Bake the Pot Pie

  1. Preheat the oven to 400°F (200°C).
  2. On a lightly floured surface, roll one sheet of thawed puff pastry into a 12-inch square. Press it into an 8″ x 8″ casserole dish, trim any excess, and prick the bottom and sides with a fork.
  3. Cover the dough with aluminum foil and par-bake the bottom crust for 25 minutes. Remove the foil.
  4. Spoon the cooled short rib and onion filling into the pre-baked crust and top with the shredded Gruyère.
  5. Roll out the second pastry sheet slightly thinner, place it over the filling, trim, and cut four 2-inch diagonal vents in the top. Whisk the egg with a teaspoon of water and brush the top with egg wash.
  6. Bake for 25 minutes, or until the puff pastry is puffed and golden brown. For even baking, position the dish in the lower half of the oven so the filling is bubbling and the crust crisps.

Notes

  • Keep an eye on the pot pie during the final minutes of baking to avoid over-browning. If needed, tent the top with foil.
  • Do not assemble the pot pie with frozen or partially thawed puff pastry. Always thaw the sheets completely before rolling.
  • To make mini pot pies: roll each pastry sheet thinner, cut 5-inch circles, press into a muffin tin, par-bake 10–12 minutes, fill with ~3 tablespoons of filling and a bit of grated Gruyère, then bake 8 minutes until golden.
  • This recipe yields enough filling for approximately 28 mini pies, which requires three sheets of puff pastry.
