Spanish Onion & Garlic Potatoes | Patatas a la Cebolla y Ajo Recipe

In this post, I´m going to show you how to make a Spanish potato dish, that´s not only going to change the way you cook potatoes, but most likely become your go-to potato dish. We are talking Spanish Onion & Garlic Potatoes.

Spanish Onion & Garlic Potatoes
These potatoes have the most incredible flavors & textures, the dish is super easy to make and it´s all done with simple everyday ingredients. Folks, this is, what great food and Spanish cuisine is all about.

Spanish Onion & Garlic Potatoes
To make this dish, I used new potatoes. But you can use any potatoes you like. Just try to use potatoes that are more waxy than starchy. That way when you cook them, they don´t fall apart and they keep their shape.

Spanish Onion & Garlic Potatoes
TIPS & TRICKS to Make this Recipe: I used vegetable broth to flavor the potatoes and to create the sauce, but you can use water. Just make sure to season accordingly. It took me 20 minutes to perfectly cook the potatoes with the broth. You don´t want to over-cook them, otherwise they might get mushy and lose their shape.

Servings 4
Author Albert Bevia @ Spain on a Fork


  • 1/3 cup extra virgin olive oil 80 ml
  • 2 potatoes
  • 1 onion
  • 4 cloves garlic
  • 1 tbsp all-purpose flour 8 grams
  • 1/2 cup white wine 118 ml
  • 1/4 cup finely chopped parsley 15 grams
  • 2 cups vegetable broth 475 ml
  • sea salt & black pepper


  1. Cut 2 peeled potatoes into rounds that are 3/4 inch (1 cm) thick

  2. Heat a large fry pan with a medium heat and add in 1/3 cup (80 ml) extra virgin olive oil

  3. After 2 minutes add in the rounds of potatoes into the pan, make sure they´re all in a single layer, cook in batches, fry for 3 minutes per side, just enough to slightly fry them, once they are all cooked, season with sea salt & black pepper and set aside

  4. Using the same pan with the same heat, add in 1 onion rougly diced and 4 cloves garlic roughly minced, mix with the olive oil, after 3 minutes and the onion is translucent, add in 1 tbsp (8 grams) all-purpose flour and continue to mix, after 2 minutes add in 1/2 cup (118 ml) white wine, 1/4 cup (15 grams) finely chopped parsley and season with sea salt & black pepper, mix until you form a thick sauce

  5. Once the sauce has thickened, add the slices of fried potato back into the pan, they can be stacked above each other, then add in 2 cups (475 ml) vegetable broth and bring to a boil, place a lid on the pan and simmer on a medium heat

  6. After simmering for 20 minutes, remove the lid, there should be some broth left but the potatoes fully cooked, just pierce with a toothpick, if it easily goes in, they are done, remove the pan from the heat

  7. Transfer the potatoes into a serving dish, spoon the left over sauce in the pan over the potatoes and sprinkle with freshly chopped parsley, enjoy!

    Another spectacular recipe for which I am eternally grateful 😁

    I have been making my way through all of your recipes with my focus so far being on the potato dishes and rice dishes.

    My husband said to me while eating dinner today, “I think you’re going to turn me into a potato lover” – from someone who always protested against potatoes, this is simply wonderful!

    Thank you, you’ve made dinner time an absolute pleasure ❤️

    My husband’s new favorite! The flavorful potatoes just melt in your mouth, incredibly delicious. Went amazing with grilled chicken and sangria! I used chicken broth and dried parsley since that was what I had handy (sorry!), absolutely love your recipes! Working my way thru them is a great culinary treat for us. Thank you!
