Step by Step Instructions (with Images)
This section features step-by-step photos for visual reference. The complete recipe can be found by scrolling to the recipe card at the bottom of the post.
- Heat oil in a large saucepan over medium-high heat. Reduce to low heat and sauté onion, carrots, celery, and garlic until softened. Stir in tomato paste, lentils, tomatoes, balsamic vinegar, Worcestershire sauce (if using), bay leaf, and 1 cup of vegetable broth/stock. Simmer for approx. 30 minutes until lentils are soft and the sauce thickens adding more stock as needed
- Meanwhile cook the sweet potatoes. Place them in a large pot of boiling water and simmer for approx. 15 minutes, until soft. Drain the potatoes and return them to the pot. Leave for a minute, shaking the pot occasionally to encourage the evaporation of any excess water. Mash the potatoes thoroughly with a potato masher.
- Transfer the lentil mixture to a baking dish in an even layer. Top the lentil base with the sweet potato mash. Optionally, sprinkle cheese on top.
- Bake in the oven for approx. 15 mins, until heated through and golden brown on top.
Top Tips & Variations
- Take Your Time: Don't rush the dish; sautéing the veggies for at least 10 minutes adds flavour depth.
- Perfect Lentil Filling: Ensure lentils are cooked and the filling has thickened. It should be saucy but not sloppy.
- Allow Lentil Mixture to cool: Although not necessary, allowing the mixture to cool will allow the lentils to support the mash better.
- Dry Potatoes: After cooking, don't skip the steam drying to prevent watery potatoes that might sink into the juicy filling; this also enhances flavour.
- Individual Portions: If preparing for a baby or toddler, consider using small ovenproof dishes for individual portions. This way, you can easily adjust the seasoning for the rest of the mixture.
- Vegan Cottage Pie: For a plant-based version, omit Worcestershire sauce and cheese.
- Delicious Swaps: Experiment with variations like swapping sweet potatoes for creamy mashed potatoes or a carrot and potato mash.
Storage and Re-heating Instructions
- Refrigerate: Allow the pie to cool completely, then store leftovers covered or in an airtight container. Refrigerate for 2 days
- Freeze: Either freeze directly after assembling, before baking or after baking. Allow the pie to cool completely, then wrap well. Wrap in a layer of cling film (plastic wrap), followed by a layer of aluminium foil, Label and freeze for up to 3 months.
- Reheating: If frozen, defrost in the refrigerator overnight and then remove the covering. Bake the pie as per the original instructions but extend the baking time to 30 mins to ensure thorough heating.
Recipe FAQs
This pie can be introduced to babies once they have started solids and are developmentally ready, typically around 6 months old. However, there are a few considerations to keep in mind.
- Skip the Worcestershire sauce, and skip/reduce the cheese to reduce sodium levels. Do not season baby portions.
As with all new foods, create a safe eating environment and closely supervise your baby during mealtime.
Not personalised advice - for informational purposes only. Consult with your paediatrician regarding the introduction of solid foods and any potential allergy risks for your baby.
Enjoy the pie on its own for a satisfying meal, or pair it with a side of mixed vegetables or salad for added freshness and nutrition.
For a hearty touch, serve with crispy bread or crusty rolls to soak up the delicious flavours of the pie.

Delicious! My 9 month old loved it and so did I. I baked slightly longer, added 1/2 cup ground beef to the lentil mixture, and used 2 cups of Mutti tomato purée as the tomato ingredients because I didn’t have chopped tomatoes. It is an incredibly filling dish and very flavorful. This was the first dish I’ve made that my little one and I could share. So grateful I found your site! Thank you for sharing your wisdom 🙂
Amy
Thanks Kaylie, so glad you enjoyed it 🙂

Hi Amy, thanks for sharing this recipe. This was so delicious, and it tasted even better the next day! I didn't have celery, so I subbed it with some mushrooms. I'll also be adding more cheese on top next time. Will definitely be cooking it again. Thank you!
Amy
Thanks, Jacinta. You can never add too much cheese! 😉
