Ingredients – French Onion Potato Bake
To make this delicious French Onion Potato Bake, you will need:
- 4–5 medium potatoes (thinly sliced)
- 2 large onions (sliced thinly)
- 2 tablespoons butter
- 2 tablespoons olive oil
- 2 cloves garlic (chopped)
- 1 cup heavy cream (or cooking cream)
- 1 cup milk
- 1 ½ cups grated cheese (cheddar, mozzarella, or a mix)
- 1 packet French onion soup mix (for extra flavor)

Step by Step Process – French Onion Potato Bake
Follow these easy steps to make your French Onion Potato Bake at home:
Step 1: Prepare the onions
- In a large pan, heat butter and olive oil together.
- Add the sliced onions and cook slowly over medium heat until they turn golden brown. This can take about 15–20 minutes. Stir often to make sure they don’t burn.
- Add garlic near the end and cook for another minute. This will give your onions a nice, sweet flavor.
Step 2: Prepare the potatoes
- Wash and peel the potatoes.
- Slice them thinly (about ¼ inch thick). Thin slices help the potatoes cook evenly.
- Keep the slices in a bowl of water while you work, so they don’t turn brown.
Step 3: Make the creamy sauce
- In a saucepan, mix together the cream, milk, and French onion soup mix.
- Heat gently while stirring, but do not let it boil.
- Once well combined, remove from heat.
Step 4: Layer the bake
- Preheat your oven to 180°C (350°F).
- In a baking dish, spread a thin layer of cream sauce at the bottom.
- Add a layer of sliced potatoes.
- Sprinkle some caramelized onions on top.
- Add a handful of grated cheese.
- Repeat the layers (potatoes, onions, cheese, sauce) until everything is used.
- Finish with a layer of cheese on the very top.
Step 5: Bake
- Cover the baking dish with foil and bake for about 40 minutes.
- Remove the foil and bake for another 15–20 minutes until the top is golden and bubbly.
- Let it cool for 5–10 minutes before serving.
And there you have it — a rich, cheesy, and comforting French Onion Potato Bake that everyone will love
