Cheesy Vegan Potato and Onion Puff Pastries INGREDIENTS:
Below are notes about the ingredients before we get into the full recipe located lower in this post on how to make these cheesy vegan puff pastries:
- oil – We are using olive oil for this recipe. Oil adds a richness, but also helps to saute the ingredients properly with optimal flavor
- onions – we are using a yellow onion for this recipe. It compliments that potatoes very well
- agave – a little sweetness to a very savory dish helps, but also adding in sugar also helps to caramelize the onions a bit faster since we aren’t letting them sit for very long
- salt, pepper, thyme, parsley, garlic – our aromatics of the dish. These ingredients start the base layers of flavor and really big the dish to another level
- potatoes – you can use yukon or russet potatoes for this diced. In order to avoid any super large pieces and make these easier to cook and eat, we recommend dicing the evenly and small.
- vegan cheddar cheese – You want a vegan shredded cheese that will meltable. You can use our shredded vegan cheese list to help
- vegan parmesan – we are using Violife in the post for this recipe.
- coconut cream – this is the thick part of a can of coconut milk. This thick cream is delicious in this recipe and helps make it a little saucy before baking
- dijon mustard – this mustard is tangy, with a sharp flavor and really enhances the onions and potatoes even though only a little is used
- puff pastry – Pepperidge Farm puff pastry is accidentally vegan and that’s what we are using here.
- everything bagel seasoning – the predominant flavor in everything bagel seasoning is the onion so it’s just another added layer of flavor
SUBSTITUTIONS AND VARIATIONS:
- oil – you can use another oil or vegetable stock to saute the veggies
- onions – sweet onions would work as well.
- agave – maple syrup or date syrup are other options for the agave
- potatoes – Switch it up and try sweet potatoes!
- vegan cheddar cheese – You could also try mozzarella or a smoked cheese like gouda or something similar
- coconut cream – vegan sour cream would be a substitute here. Any non-dairy milk will technically work as well, but the thicker variations are better in our opinion
- puff pastry – you could stuff pre-made croissant dough as well
- everything bagel seasoning – try another pre-made seasoning blend instead
