Preheat your oven to 400 degrees. Lightly grease a baking dish.
In a large skillet over medium heat, cook the ground beef until browned. Break it up with a spoon as it cooks. Drain any extra grease.
Add chopped onion and carrots. Cook for about 5 minutes, until softened. Stir in the garlic and cook for 1 more minute.
Stir in tomato paste, beef broth, and Worcestershire sauce. Let it simmer for 8 to 10 minutes, until slightly thickened. Season with salt and pepper.
Spread the beef mixture evenly in your baking dish.
Top with warm mashed potatoes. Use a fork to gently spread them and create little ridges on top. Those ridges turn golden and crisp in the oven.
Bake for 20 to 25 minutes, until the top is lightly golden and the edges are bubbling.
Let it rest for 5 to 10 minutes before serving. This helps it set and makes scooping easier.

FAQs

Is this the same as traditional shepherd’s pie?

Traditional shepherd’s pie is usually made with lamb. Cottage pie uses ground beef instead. This version is perfect if you are looking for things to make with ground beef that still feel classic and comforting. The flavor is rich and hearty, and most families already have ground beef on hand. It is a simple swap that keeps the spirit of the dish.

Can I make this ahead for St. Patrick’s Day?

Yes, and I highly recommend it. You can assemble the whole dish, cover it, and store it in the fridge for up to 24 hours before baking. When you are ready, bake as directed. It may need a few extra minutes if it goes into the oven cold. This makes it one of my favorite St. Patrick’s Day recipes for busy families.

What are other dinner ideas with ground beef?

Ground beef is so versatile. You can turn it into tacos, pasta sauces, casseroles, or skillet meals. If you ever wonder about things to do with ground beef, think simple and comforting. Burgers, meatballs, and stuffed peppers are all easy options. It is one of those ingredients that saves the day.

Can I freeze Irish Cottage Pie?

Yes, this dish freezes beautifully. Let it cool completely, then wrap it tightly and freeze for up to 3 months. Thaw overnight in the fridge before reheating. It is one of those ground hamburger recipes that tastes just as good the second time around.
