There are some recipes that don’t need to be complicated to be absolutely unforgettable. This is one of them. Golden, crispy-edged potatoes pan-fried in rich butter, tossed with sweet caramelized onions, a touch of Cajun seasoning, and finished with a bright scatter of fresh parsley — this is the kind of side dish that steals the spotlight every single time it hits the table.
Whether you’re serving it alongside roasted chicken, grilled steak, or a simple breakfast spread, these buttery fried potatoes and onions deliver maximum comfort with minimal effort.
Why This Recipe Works
The secret to this dish is a two-step cooking method — boiling the potatoes first until just fork-tender, then finishing them in a hot buttered skillet. This gives you the best of both worlds: a fluffy, fully cooked interior and a beautifully golden, crispy exterior that you simply can’t achieve by frying raw potatoes alone.
The onions caramelize gently in the butter, adding a natural sweetness that balances the savory seasoning perfectly. And the fresh parsley? It goes in right at the very end — keeping its color bright and its flavor clean and vibrant rather than wilted and dull.
Ingredients
6 to 8 medium potatoes, peeled and quartered
Salt, for boiling water
1 medium onion, halved and thinly sliced
1 stick (113g) unsalted butter
1 teaspoon Cajun seasoning
1½ teaspoons garlic salt with parsley
Salt and black pepper to taste
¼ cup bacon grease or neutral oil (optional, for extra crispiness)
1 to 2 tablespoons fresh parsley, chopped
Step-by-Step Instructions
Step 1 — Boil the Potatoes
Place the peeled, quartered potatoes in a large pot and cover with cold water. Season the water generously with salt. Bring to a boil and cook for 12 to 15 minutes, or until the potatoes are just fork-tender — cooked through but not falling apart. Drain thoroughly and let them steam dry in the colander for a few minutes. This step removes excess moisture, which is key to getting crispy edges in the pan.
Step 2 — Heat the Pan
In a large cast iron skillet or heavy-bottomed frying pan, melt the butter over medium heat. If using bacon grease or oil, add it alongside the butter at this stage. The combination of butter and a higher smoke point fat gives you richer flavor and better crispiness without burning.
Step 3 — Caramelize the Onions
