Why This Beef Wellington Casserole is a Weeknight Win

This version of Beef Wellington with ground beef is a clever and time-saving spin on a classic.

What makes this version truly shine is its simplicity. You get all the same satisfying textures and flavors—savory meat, tender veggies, rich pastry—but without the stress of working with expensive meat cuts or intricate wrapping.

What is Beef Wellington Casserole?

How to Make Beef Wellington Casserole (Step-by-Step)

1. Preheat and Prepare
   Start by preheating your oven to 400°F (200°C) and lining a baking sheet with parchment paper.
2. Cook the Veggies
   In a large skillet, melt butter over medium heat. Add chopped onions and mushrooms, sautéing until soft and the moisture is mostly gone. Add garlic and cook for another minute.
3. Brown the Beef
   Stir in the ground beef, breaking it up with a spoon. Season with salt, pepper, and steak seasoning. Cook until browned and no longer pink. Drain any excess fat.
4. Flavor It Up
   Stir in Worcestershire sauce and Dijon mustard. Mix well to combine all the flavors. Let the mixture cool slightly before assembling the casserole.
5. Roll the Puff Pastry
   On a lightly floured surface, roll out your thawed puff pastry to smooth any creases. Transfer it to the prepared baking sheet.
6. Assemble the Casserole
   Spoon the cooled beef mixture into the center of the pastry. Fold the sides over like a burrito or rectangle to seal it. Pinch edges closed and place seam side down.
7. Brush and Bake
   Beat the egg and brush it all over the top of the pastry. Bake for 20–25 minutes, or until golden brown and puffed.
8. Cool and Serve
   Allow to cool for 5–10 minutes before slicing and serving.
