Ingredients:
- 1 tablespoon olive oil
- 1 large onion, finely chopped
- 2 carrots, peeled and diced
- 2 celery stalks, diced
- 2 cloves garlic, minced
- 1 pound cremini mushrooms, sliced
- 1 (14.5 ounce) can diced tomatoes, undrained
- 1 (15 ounce) can lentils, drained and rinsed
- 1 cup vegetable broth
- 1 teaspoon dried thyme
- 1/2 teaspoon dried rosemary
- 1/4 teaspoon red pepper flakes (optional)
- Salt and freshly ground black pepper to taste
- For the Mashed Potato Topping:
- 2.5 pounds russet potatoes, peeled and quartered
- 1/2 cup milk (or plant-based milk)
- 4 tablespoons butter (or vegan butter)
- Salt and freshly ground black pepper to taste
- 1/4 cup grated Parmesan cheese (optional, or nutritional yeast for vegan)
Preparing the Vegetable Filling
- Sauté the Aromatics: First, heat the olive oil in a large, deep skillet or Dutch oven over medium heat. Add the chopped onion, carrots, and celery. Cook, stirring occasionally, until the vegetables are softened, about 8-10 minutes. You want them to be tender and slightly translucent. Don't rush this step; allowing the vegetables to soften properly builds a good flavor base for the entire dish.
- Add Garlic and Mushrooms: Next, add the minced garlic and sliced mushrooms to the skillet. Cook, stirring frequently, until the mushrooms have released their moisture and are nicely browned, about 5-7 minutes. The browning of the mushrooms is key to adding depth of flavor. If the pan seems dry, add a splash more olive oil.
- Incorporate Tomatoes and Lentils: Now, stir in the can of diced tomatoes (undrained), drained and rinsed lentils, vegetable broth, dried thyme, dried rosemary, and red pepper flakes (if using). Bring the mixture to a simmer.
- Simmer and Season: Reduce the heat to low, cover the skillet, and let the vegetable filling simmer for at least 20 minutes, or up to 30 minutes, stirring occasionally. This allows the flavors to meld together beautifully and the sauce to thicken slightly. Season generously with salt and freshly ground black pepper to taste. Remember to taste as you go and adjust the seasoning as needed. A little extra pepper can really enhance the savory notes.
Making the Mashed Potato Topping
- Boil the Potatoes: While the vegetable filling is simmering, prepare the mashed potato topping. Place the peeled and quartered russet potatoes in a large pot and cover them with cold water. Add a pinch of salt to the water. Bring the water to a boil over high heat, then reduce the heat to medium and cook until the potatoes are fork-tender, about 15-20 minutes. You should be able to easily pierce them with a fork.
- Drain and Mash: Once the potatoes are cooked, drain them thoroughly in a colander. Return the drained potatoes to the pot. Add the milk (or plant-based milk) and butter (or vegan butter). Using a potato masher or an electric mixer, mash the potatoes until they are smooth and creamy. Be careful not to overmix, as this can make the potatoes gluey.
- Season and Flavor: Season the mashed potatoes generously with salt and freshly ground black pepper to taste. If desired, stir in the grated Parmesan cheese (or nutritional yeast for a vegan option) for added flavor. Taste and adjust the seasoning as needed. The mashed potatoes should be well-seasoned, as they will be topping the flavorful vegetable filling.
Assembling and Baking the Cottage Pie
- Preheat the Oven: Preheat your oven to 375°F (190°C).
- Transfer Filling to Baking Dish: Pour the prepared vegetable filling into a 9x13 inch baking dish or a similar-sized oven-safe dish. Make sure the filling is evenly distributed in the dish.
- Top with Mashed Potatoes: Carefully spoon the mashed potato topping over the vegetable filling, spreading it evenly to cover the entire surface. You can create a decorative pattern on top of the mashed potatoes using a fork, if desired. This not only looks nice but also helps to create crispy edges.
- Bake the Cottage Pie: Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the mashed potato topping is golden brown and the filling is bubbling around the edges. Keep a close eye on it during the last few minutes of baking to prevent the topping from burning.
- Rest Before Serving: Remove the cottage pie from the oven and let it rest for at least 10 minutes before serving. This allows the filling to set slightly and makes it easier to serve.
Tips and Variations
Spice it Up!
If you like a bit more heat, increase the amount of red pepper flakes or add a pinch of cayenne pepper to the vegetable filling.
Add More Vegetables!
Feel free to add other vegetables to the filling, such as peas, corn, green beans, or chopped bell peppers. Just adjust the cooking time accordingly.
Make it Vegan!
To make this recipe vegan, use plant-based milk and vegan butter for the mashed potato topping, and substitute nutritional yeast for the Parmesan cheese.
Use Different Lentils!
While I prefer brown or green lentils for this recipe, you can also use red lentils. Keep in mind that red lentils cook faster and may become mushier, so adjust the cooking time accordingly.
Make Ahead!
You can prepare the vegetable filling and mashed potato topping ahead of time and store them separately in the refrigerator for up to 2 days. When ready to bake, assemble the cottage pie and bake as directed.
Freezing Instructions!
This cottage pie can also be frozen for later. Assemble the pie in a freezer-safe dish, let it cool completely, then wrap it tightly with plastic wrap and aluminum foil. Freeze for up to 3 months. To bake from frozen, thaw the pie in the refrigerator overnight, then bake as directed, adding an extra 10-15 minutes to the baking time.

This vegetarian cottage pie is delicious on its own, but it also pairs well with a side salad or steamed green vegetables.
