How to Make Meatloaf Wellington
1. Prep the oven and mushrooms
Preheat your oven to 400°F. Add the mushrooms to a food processor and pulse until they are finely ground and evenly chopped.
2. Cook the vegetables
Heat the olive oil in a large skillet over medium heat. Add the chopped onion and mushrooms. Cook for about 7 to 10 minutes, stirring now and then, until the mushrooms release their moisture and the onion turns soft and translucent.
Add the minced garlic and cook for another 30 seconds to 1 minute, just until fragrant. Remove from the heat and let the mixture cool slightly.
3. Make the meatloaf mixture
In a medium bowl, combine the ground beef, egg, bread crumbs, Dijon mustard, kosher salt, and black pepper. Add the cooked mushroom mixture and mix until everything is evenly combined.
Do not overmix. Just bring it together until the ingredients are well distributed.
4. Shape the loaf
Transfer the meat mixture onto a cutting board or clean work surface and shape it into a 12-inch log.
5. Wrap in prosciutto
Lay out the prosciutto and wrap it around the meatloaf, covering as much of the outside as possible. It does not have to be perfect. The prosciutto helps add flavor and creates a nice barrier between the meat and puff pastry.
6. Roll out the pastry
On a lightly floured surface, roll the puff pastry into roughly a 14 x 14-inch square.
Place the wrapped meatloaf along one edge of the pastry. Roll the pastry around the loaf until it is fully covered. Try to avoid too much overlap so the crust bakes evenly.
Trim any excess pastry with a small knife. Pinch the seam closed and seal the ends. You can lightly wet your fingers with water if needed to help the pastry stick.
7. Decorate if desired
Place the Wellington seam-side down on a sheet pan. If you want to make it look extra special, use the trimmed pastry to create simple decorative strips or shapes on top.
Cut a few small slits or poke a few holes in the pastry so steam can escape while baking.
8. Add the egg wash
In a small bowl, beat together the egg and heavy cream or milk. Brush the top and sides of the pastry with the egg wash. This gives the Wellington that beautiful glossy golden finish.
9. Bake
Bake for 30 to 35 minutes, or until the pastry is deeply golden brown and the internal temperature of the meatloaf reaches 160°F.
10. Rest and serve
Let the Meatloaf Wellington rest for 5 to 10 minutes before slicing. This helps the juices settle and makes it easier to cut clean slices.
Serve warm with mashed potatoes or colcannon.
Serving Suggestions
This dish is rich and satisfying, so it pairs well with simple sides like:
- Creamy mashed potatoes
- Colcannon
- Roasted green beans
- Buttered peas
- A crisp green salad
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days.
To reheat, place slices in the oven at 325°F until warmed through. This helps keep the pastry crisp better than the microwave.
Tips for Success
- Let the mushroom mixture cool slightly before mixing it into the beef
- Do not skip vent holes in the pastry
- Avoid overfilling or overwrapping the puff pastry
- Use a thermometer to make sure the center reaches 160°F
- Rest before slicing so the loaf holds together better
