Combine the lentil filling.
1.Fold in the cooked lentils, frozen peas, thyme, and rosemary.2.Stir gently to combine everything evenly.3.Simmer for 5 minutes to let the flavors meld. Season with remaining salt and pepper.TIPThe filling should be moist but not soupy. If it's too thick, splash in a little more water. - assemble · ~3 min
Assemble the pie.
1.Spoon the mashed potatoes over the lentil filling in dollops, then gently spread them to the edges with a spatula.2.Create a seal by pressing the potatoes against the edges of the skillet.3.Drag a fork across the top to create ridges that will brown beautifully.TIPDon't smooth the potatoes completely flat — the ridges and peaks get wonderfully crispy in the oven. - bake · ~20 min
Bake until golden and bubbling.
1.Place the skillet on a baking sheet to catch any overflow.2.Bake at 400°F for 20 minutes, or until the top is golden brown and the filling is bubbling around the edges.3.Sprinkle a pinch of paprika over the top in the last 2 minutes for color.TIPFor an extra-crispy top, switch to broil for the final 2-3 minutes — keep a close eye on it. - rest · ~10 min
Rest before serving.
Let the pie sit for 10 minutes after baking. This helps the filling set so it doesn't spill out when you scoop.
TIPSkipping the rest means a soupy first serving. Patience pays off here.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Simmer the lentils gently — a rolling boil will split them and ruin the texture.
- 2Let the drained potatoes steam dry for a minute before mashing to avoid watery potatoes.
- 3Don't skip resting the pie for 10 minutes after baking; it lets the filling set for clean slices.
- 4Use an oven-safe skillet to save on cleanup and keep the pie piping hot.
- 5For a crispier potato top, broil for the last 2-3 minutes and watch closely.
- 6Resist smoothing the mashed potatoes flat — ridges create crispy, golden peaks.
