Section: Wholesome Meals for Every Day

Layers of seasoned lentils and roasted butternut squash meld together beneath a golden, buttery mashed potato topping in this fall-inspired casserole. Slow-simmered lentils create a deeply flavored base, while roasted squash adds sweetness and depth. Onion, garlic, thyme, and smoked paprika build an inviting, rustic aroma throughout the baking dish. Once topped with a creamy mashed layer and baked until bubbling, each slice offers textural contrast—rich, earthy filling balanced by a light, crisp potato crust. It’s a hearty, comforting main perfect for chilly evenings and easily adaptable for leftovers.

Nothing makes my kitchen feel cozier than assembling a Fall Lentil Shepherds Pie with roasted squash and creamy mashed potatoes. This dish packs warmth into every bite with its thick, rustic lentil base and pillowy golden topping. It is one of those autumn dinners that feels both nourishing and deeply satisfying whether I am cooking for a crowd or just seeking comfort on a chilly weeknight.

The first time I made this pie I worried my meat lovers would miss the original but it quickly disappeared at the table—no one even mentioned the change because the lentil and roasted squash filling is that good.

Ingredients

  • Dried green or brown lentils: Choose fresh lentils that are whole and glossy for best texture They soak up broth and become tender little flavor carriers
  • Vegetable broth: Use a good quality low sodium broth for depth and balance in the lentil mix
  • Butternut squash: Pick a small heavy squash with rich orange flesh It roasted sugars lend subtle sweetness and seasonal flavor
  • Olive oil: For both roasting and sautéing Use a fruity extra virgin oil if possible for extra depth
  • Onion: Select a fresh firm onion The sauté will form a sweet base for the filling
  • Garlic: Fresh cloves give the best punch Use plump cloves that feel heavy and solid
  • Thyme: Dried or fresh Either works A crucial earthy element—if using fresh strip the leaves first
  • Smoked paprika: Optional yet magical look for a deep red powder to add a subtle smoky depth
  • Mashed potatoes: Creamy and smooth prepared with butter and milk Choose Yukon Gold for the richest flavor and fluffiest texture
  • Salt and pepper: Taste and season as you go for a perfectly savory result

Instructions

Prepare Lentils:
Rinse the lentils thoroughly under cool water until the water runs clear This step removes dust and helps avoid mushiness Combine lentils and vegetable broth in your large saucepan Bring to a gentle boil then immediately lower to a simmer Cover and cook slowly for about twenty to twenty five minutes stirring once or twice until the lentils are tender and most liquid is absorbed
Roast Squash:
While lentils are simmering set your oven to four hundred degrees Fahrenheit Two hundred degrees Celsius Toss the prepared cubes of butternut squash with half your olive oil and arrange in a single layer on a baking sheet Roast for about twenty to twenty five minutes stirring once midway through You are looking for the edges to caramelize and the flesh to become fork tender
Sauté Aromatics:
Heat the remaining olive oil in a wide skillet over medium heat Add your chopped onion and let it sweat gently for about five minutes Stir often as a golden edge begins to appear and a sweet aroma fills the pan Add the minced garlic and thyme Cook for one more minute being careful not to burn the garlic
Build the Filling:
Add your roasted squash into the skillet Mash some cubes lightly with your spoon as you stir and let the mixture cook for about five more minutes Sprinkle in smoked paprika salt and black pepper Adjust seasoning to preference and keep stirring gently for the flavors to meld
Combine and Thicken:
Drain any lingering liquid from the lentils and fold them into your squash onion skillet Simmer everything together for about five to seven minutes allowing the filling to become thick hearty and well blended
Assemble in Dish:
Spoon the lentil squash mixture into the bottom of your baking dish Spread into an even layer Top carefully with warm mashed potatoes Dollop potatoes first then spread with a spatula or the back of a spoon until smooth and level covering the edges to seal in moisture
Bake to Perfection:
Move your assembled dish into the preheated oven Bake for twenty minutes or until the mashed potatoes are golden and just beginning to crisp at the edges For a deeply browned crust switch the oven to broil for two to three minutes watching closely
Serve and Enjoy:
Allow the dish to cool for several minutes before cutting into generous wedges That little wait makes slicing neater and helps all the flavors settle Serve hot and savor every creamy earthy forkful

Butternut squash is always the star for me roasting brings out its buttery sweetness I always remember my kids running through the house drawn by the savory smells from the oven and sneaking hot bites before the pie hit the table

Storage Tips

Cover leftovers tightly and refrigerate for up to three days This pie reheats beautifully in the oven at three hundred fifty degrees until piping hot The mashed top might brown even more but I think it just enhances flavor For quicker lunches the microwave works too but cover the serving with a damp towel so things do not dry out

Ingredient Substitutions

If you run out of butternut squash sweet potato or acorn squash work well For lentils feel free to swap in black or French lentils just adjust simmering time Mashed potatoes can be made dairy free with olive oil and non dairy milk A teaspoon of rosemary or sage makes a nice stand in for thyme

Serving Suggestions

This shepherds pie shines as a stand alone main but you can round out the meal with a crisp green salad or garlicky sautéed greens For extra comfort I sometimes sprinkle on sharp grated cheddar before baking Fresh parsley or chives on top bring color and zing

Cultural Context

Shepherds pie started as pure comfort food in British and Irish kitchens Originally a way to stretch meat leftovers with a potato crust modern versions like this one use lentils for heartiness and nutrition without compromise My family embraced this plant based spin long before it became trendy

Seasonal Adaptations

Top with parsnip mash for winter variety Layer in sautéed mushrooms for fall richness Add frozen peas for a pop of spring sweetness

Success Stories

Every autumn I revisit this recipe as a tradition I have shared it with friends at potlucks and every time someone requests the recipe My neighbor once claimed it outshined her own holiday main which always makes me proud

Freezer Meal Conversion

You can cool and freeze the assembled unbaked pie Cover tightly and freeze for up to two months To cook bake directly from frozen at three hundred seventy five degrees for forty five to fifty five minutes until golden and hot all the way through

Ingredients You’ll Need

01 1 cup dried green or brown lentils, rinsed and drained
02 2 cups vegetable broth
03 1 small butternut squash, peeled and cubed
04 2 tablespoons olive oil, divided
05 1 medium onion, chopped

07 1 teaspoon thyme, dried or fresh
08 1/2 teaspoon smoked paprika (optional)
09 Salt and freshly ground black pepper, to taste

→ Topping

10 1 cup mashed potatoes, prepared with butter and milk

How to Make It

Step 01

Rinse lentils under cold water. In a large saucepan, combine lentils and vegetable broth; bring to a gentle boil, then reduce heat. Cover and simmer for 20–25 minutes until lentils are tender and broth is absorbed.

Step 02

Preheat oven to 200°C. Toss cubed butternut squash with 1 tablespoon olive oil. Spread on a baking sheet and roast for 20–25 minutes, stirring halfway, until soft and caramelized.

Step 03

In a skillet, heat remaining tablespoon olive oil over medium heat. Add chopped onion and sauté for about 5 minutes until translucent. Stir in minced garlic and thyme; cook for 1 minute until fragrant.

Step 04

Add roasted squash to the skillet with onions. Gently mash squash with a spoon and cook for 5 minutes to blend flavours. Add smoked paprika, salt, and pepper, adjusting to taste.

Step 05

Drain any excess liquid from cooked lentils. Fold lentils into the squash mixture and simmer for 5–7 minutes until thickened and cohesive.

Step 06

Transfer lentil filling mixture into a baking dish and smooth the surface. Top evenly with prepared mashed potatoes, smoothing with a spatula.

Step 07

Bake at 200°C for 20 minutes or until the mashed potato topping is golden and edges are crisp. For deeper browning, broil for an additional 2–3 minutes. Let rest briefly, then slice and serve warm.

Extra Tips

  1. For extra richness, sprinkle grated cheese over the mashed potato layer before baking, or garnish with chopped fresh herbs such as parsley after baking. Leftovers can be reheated in the oven or microwave.
