What Is Cottage Pie?

Cottage pie is a classic English comfort food made with minced beef cooked in rich gravy with vegetables, topped with creamy mashed potatoes, and baked until golden and crispy.

• 1 tablespoon Worcestershire sauce
• 300g (10½ oz) butternut squash, peeled and cubed
• 600ml (2½ cups) beef stock (made with 2 stock cubes)
• 1 tablespoon cornflour mixed with 1 tablespoon cold water

For the Mashed Potato Topping:

• 900g floury potatoes, peeled and cubed
• 1 teaspoon salt
• 120ml (½ cup) potato cooking water (reserved)

How to Make Healthy Cottage Pie

Make the Beef Filling:

Step 1: Sauté Aromatics Spray a large casserole dish with olive oil spray. Add onions and cook over medium heat for 2 minutes until slightly softened.

Step 2: Add Vegetables and Seasonings Stir in garlic, carrots, celery, salt, herbs, brown sugar, and bay leaves. Cook for 8 minutes, adding a splash of stock if the pan gets too dry.

Step 3: Brown the Beef Add lean beef mince, breaking it up with a wooden spoon. Cook until nicely browned all over.

Step 4: Build Flavor Stir in tomato puree, then add balsamic vinegar, soy sauce, and Worcestershire sauce. Mix well.

Step 5: Add Squash and Stock Stir in butternut squash cubes and beef stock. Bring to a simmer, partially cover, and cook for 30 minutes.

Step 6: Thicken the Gravy Add cornflour slurry (cornflour mixed with water) and simmer for 2 minutes until gravy thickens. Remove bay leaves. Use a fork to lightly mash some of the squash for extra body. Taste and season if needed.

Make the Mashed Potato Topping:

Step 7: Cook Potatoes While filling simmers, bring a large pot of salted water to boil. Add potatoes and cook until fork-tender, about 15 minutes. Drain, reserving 120ml (½ cup) of the starchy cooking water.

Step 8: Create Creamy Mash Mash potatoes using a potato masher or ricer, adding some reserved cooking water to help achieve a smooth consistency. Add fromage frais and mash until creamy, fluffy, and smooth. Stir in parsley (optional). Season with salt and pepper to taste.

Assemble and Bake:

Step 9: Layer the Pie Preheat oven to 220°C/400°F. Transfer beef filling to an ovenproof dish and pack down. Spoon mashed potato over the meat, using the back of a spoon to fill gaps and create a scalloped pattern with ridges.

Step 10: Top and Bake Sprinkle grated Parmesan over the top. Bake for 30-35 minutes until mash is golden and filling bubbles at the edges.

Step 11: Rest and Serve Cool for 10-15 minutes. Sprinkle with parsley and serve with green vegetables like peas or green beans.

Pro Tips for Perfect Healthy Cottage Pie

Use Lean Beef – 5% fat mince keeps calories down while maintaining great flavor

Don’t Skip the Squash – Butternut squash adds nutrition, stretches the filling, and adds natural sweetness when mashed

Mash Some Squash – Lightly mashing some squash pieces thickens the gravy naturally

Reserve Potato Water – The starchy water makes mashed potatoes creamier without adding calories

Season the Mash – Don’t let your topping be bland! Proper seasoning is essential

Create Ridges – Scalloped patterns on the mash create crispy, golden edges

Let It Rest – Cooling for 10-15 minutes helps everything set for easier serving

Make It Lower Calorie – Replace potatoes with mashed swede (rutabaga) for even fewer calories

Storage and Make-Ahead Instructions

Make-Ahead: Assemble the entire pie up to 24 hours in advance. Cool, cover, and refrigerate. Bake straight from the fridge at 200°C/400°F for 30-35 minutes.

Refrigerator: Store leftover cottage pie covered in the fridge for up to 3 days. Reheat individual portions in the microwave or reheat larger portions in the oven at 180°C/350°F until heated through.

Freezer: Freeze assembled (unbaked) pie. Cool completely, cover tightly, and freeze for up to 2 months. Defrost overnight in the fridge, then bake at 200°C/400°F for 30-35 minutes until golden and bubbling.

Individual Portions: Create mini cottage pies in ramekins or small oven-safe dishes for perfect single servings. Great for portion control and meal prep!

Recipe Variations and Substitutions

Non-Diet Version – Use regular beef mince, add butter to the mash, and use sour cream instead of fromage frais

Gluten-Free – Use Tamari instead of soy sauce and ensure stock cubes are gluten-free

Vegetarian Cottage Pie – Replace beef with cooked lentils or lentil ragu. Use vegetable stock and vegetarian hard cheese

Lower Carb – Replace mashed potatoes with mashed swede (rutabaga) or cauliflower mash

Different Vegetables – Add mushrooms, parsnips, or other root vegetables to the filling

Extra Protein – The lean beef provides plenty of protein, but you can add red lentils to the filling for even more

Cheese Options – Use reduced-fat cheddar or skip cheese entirely to reduce calories further

Sweetener Note – If using artificial sweetener instead of brown sugar, use half the amount as some sweeteners are twice as sweet as sugar

Serving Suggestions

Classic Pairing: Serve with steamed green beans, peas, or broccoli for a complete, balanced meal.

Extra Veggies: Load your plate with sugar snap peas, Brussels sprouts, or roasted vegetables to make it even more filling and nutritious.

Side Salad: A fresh green salad with a light vinaigrette adds freshness and crunch.

Portion Control: One serving is approximately ⅙ of the pie—perfect for staying on track with your diet goals!
