Instant Pot Cottage Pie
This Instant Pot Cottage Pie is an easy, streamlined version of the classic comfort food made with ground beef, vegetables, and a creamy mashed potato topping.
Ingredients
- 1 pound ground beef
- 1 onion, diced
- 1 cup frozen mixed vegetables
- 1 cup mushrooms, sliced
- 2 garlic cloves, minced
- 1 can diced tomatoes
- 2 teaspoons dried thyme
- 1 teaspoon dried oregano
- 1 teaspoon salt
- 2 tablespoon tomato paste
- 1 cup cheddar cheese, shredded
- ½ pound russet potatoes, peeled and quartered
- 2 tablespoons butter
- 2 tablespoons milk
Instructions
- Set the Instant Pot to Sauté and add a small amount of oil. Add the ground beef and diced onion and cook, breaking up the beef, until browned and the onion is softened. Drain excess fat if needed.
- Stir in the frozen mixed vegetables, mushrooms, garlic, diced tomatoes, dried thyme, dried oregano, salt, and tomato paste. Mix well to evenly combine.
- Place the wire rack on top of the beef mixture, making sure it sits securely above the liquid. Carefully place the quartered potatoes on the rack. Do not stir after adding the rack.
- Seal the Instant Pot and cook on Manual (High Pressure) for 10 minutes. When cooking is complete, use quick release to release the pressure.
- Carefully remove the potatoes and transfer them to a bowl. Mash with the butter and milk until smooth, seasoning with salt and pepper to taste.
- Transfer the beef and vegetable mixture to a 9×13-inch baking dish. Spread the mashed potatoes evenly over the top, then sprinkle with shredded cheddar cheese.
- Place the dish under the broiler for a few minutes, just until the cheese is melted and lightly browned. Serve warm.

Notes
- Use the rack for the potatoes: Keeping the potatoes elevated allows them to steam instead of boil, which helps prevent watery mashed potatoes.
- Do not stir after adding the rack: Stirring once the rack is in place can push food underneath it and increase the risk of a burn notice.
- Mash potatoes while hot: Warm potatoes mash more smoothly and absorb butter or dairy-free alternatives better.
- Watch the broiler closely: The cheese browns quickly under the broiler, so keep a close eye to avoid burning.
- Taste the filling before assembling: Adjust salt and seasoning if needed before topping with the mashed potatoes.
