Potato Leek Soup
This creamy Potato Leek Soup recipe is rich & cozy, made with buttery leeks, tender potatoes, and a few simple techniques for the best texture.
This Potato Leek Soup is a quiet triumph of simplicity and depth-leeks caramelized to golden sweetness, potatoes softened into a velvety base, and a whisper of vinegar to cut through the richness. It's a dish that honors seasonal ingredients without pretension, relying on butter and cream to elevate humble vegetables into something comforting and satisfying, exactly as it should be.
Instructions
- 1
Boil potatoes (skin on) until fork tender, 15-20 minutes.
- 2
Meanwhile, trim and clean leeks. I separate the tough outer layers and the ends from the tender, inner layers. You want to use the inner layers in your soup!
- 3
Rinse any dirt off the tough outer leaves and ends and save it for future stock. Nothing goes to waste in our budget-friendly kitchen!
- 4
Mince the green onion, leeks, and garlic.
- 5
Strain potatoes once fork tender.
- 6
Melt butter and oil in the same pot you boiled the potatoes in and add prepared leeks, garlic, salt, and black pepper. Sauté until softened, about 8 minutes over medium heat.
- 7
Dice 2 cups of the potatoes into ½” pieces. Set aside.
- 8
Add whole potatoes, thyme, bay leaf, apple cider vinegar, and vegetable broth to the pot with the sauteed leeks. Bring to a simmer.
- 9
Mash the potatoes in the pot while simmering.
- 10
Remove bay leaf and thyme stem. Temper the cream by adding some of the hot broth to the room temperature heavy cream.
- 11
Add the tempered cream to the pot and turn the heat down to low, simmering for 5-8 minutes.
- 12
Ladle half of the soup broth (with chunks of potatoes and leeks included) into a blender. Let it cool for a few minutes before blending until smooth.****
- 13
Pour the pureed soup back into the simmering pot with the rest of the soup.
- 14
Add the green onions and reserved diced potatoes into the pot.
- 15
Adjust seasoning with additional salt and pepper, if desired. (Add corn starch to thicken by creating a slurry, if desired.) Serve and enjoy.

French Fish Pie
Recipe video above. This is a homestyle fish pie I like to make for Easter, one of my mother used to make for us. Chunks of white fish fillets slowly poached in creamy béchamel with fennel, leek and fresh dill then topped with mashed potato and baked until golden. Don't be surprised that it doesn’t call for a homemade fish stock, you’ll still get plenty of flavour from the fish itself and the fresh herbs.
