Comfort food made easier: Classic cottage pie flavors without the long simmer or extra steps.
Great for weeknights: Straightforward ingredients and a streamlined process make this practical for busy evenings.
Key Ingredients:
- ground beef. Forms the base of this cottage pie and cooks quickly in the Instant Pot, making the recipe faster than traditional versions.
- frozen mixed vegetables. Add color and texture with minimal prep, keeping this recipe weeknight-friendly.
- diced tomatoes & tomato paste: This combo creates a rich, slightly tangy sauce that binds the filling together.
- russet potatoes. Steam on a rack in the Instant Pot and mash easily into a smooth, creamy topping.
- cheddar cheese. Finishes the dish with a lightly browned, familiar topping after broiling.
Scroll to the recipe card at the bottom of this page for exact quantities.
Easy Substitutions & Variations:
- Make it dairy-free: Skip the cheese and mash the potatoes with dairy-free butter and unsweetened dairy-free milk (such as almond or oat milk).
- Swap the vegetables: Use peas, corn, or green beans in place of the frozen mixed vegetables.
- Use a different mushroom: Cremini or white button mushrooms both work well and add similar depth.
- Make it creamier: Add an extra tablespoon of butter or a splash more milk when mashing the potatoes (use dairy-free options if needed).
- Skip the mushrooms: Leave them out if preferred; the cottage pie will still be flavorful.
How to Make Instant Pot Cottage Pie:
- 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.

Recipe Notes & Tips:
- 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.
How to Store:
Refrigerator: Let the cottage pie cool completely, then cover tightly or transfer to an airtight container. Store in the fridge for up to 4 days.
Reheat: Warm individual portions in the microwave or reheat the full dish in a 350ºF oven for 15-20 minutes, until heated through.
Freezer: Freeze fully assembled (before or after baking) for up to 2 months. Wrap tightly in foil and plastic. Thaw overnight in the fridge and bake at 350ºF until hot.
