Greek Potatoes with Tomato Confit and Oregano
Creamy-centered potatoes roasted until golden, layered with slow-cooked tomato confit infused with oregano and garlic, topped with crumbled feta cheese. This island-style side draws inspiration from Greek hospitality—simple ingredients transformed by time and heat into something deeply satisfying. The potatoes absorb the tomato essence while the feta adds sharp, salty contrast.

Steps
Before you start
- Preheat your oven to 400°F (200°C)
- Use waxy potatoes like Yukon Gold or red potatoes so they hold their shape
- Crush the dried oregano between your palms before using to release essential oils
Start the tomato confit
- In a small saucepan, combine the crushed tomatoes, minced garlic, 1.5 tablespoons (22 ml) of the olive oil, and the dried oregano.
- Stir to combine.
- Bring to a gentle simmer over medium heat, then reduce to medium-low.
- Let it bubble gently for 25–30 minutes, stirring occasionally, until the tomato liquid has reduced by about half and the sauce becomes concentrated and jammy.
- Season lightly with salt and pepper.
- The confit is ready when the oil has darkened slightly and the flavors taste deep and sweet.

Ready when: Tomato sauce is deep red, glossy, and reduced by about half
Tip: Stir occasionally to prevent the bottom from sticking and burning
Prepare the potatoes
- While the tomato confit cooks, scrub the potatoes and cut them into 1-inch (2.5 cm) cubes—aim for uniform size so they cook evenly.
- Try to leave some skin on for texture and nutrition.
- Toss the cubed potatoes in a large baking dish with the remaining 2.5 tablespoons (37 ml) of olive oil, salt, and pepper.
- Spread them in a single layer.

Ready when: Potatoes are evenly coated and spread in a single layer
Tip: Don't crowd the pan; potatoes need space to roast and brown
Roast the potatoesOven 400°F / 205°C
- Place the baking dish in a preheated 400°F (200°C) oven and roast for 35 minutes, stirring halfway through at the 18-minute mark.
- The potatoes should be starting to turn golden and be fork-tender on the outside but still slightly firm inside.

Ready when: Potatoes are golden at the edges and fork-tender
Tip: Stir at the halfway point to ensure even browning on all sides
Layer with tomato and onion
- Remove the potatoes from the oven.
- Scatter the thinly sliced red onion evenly over the hot potatoes, then pour the entire tomato confit over the top, stirring gently to distribute.
- If using Kalamata olives, scatter them in as well.

Ready when: Tomato confit is evenly distributed over potatoes and onions
Tip: The heat of the potatoes will soften the raw onion slightly
Final roast and meltOven 400°F / 205°C
- Return the baking dish to the 400°F (200°C) oven for 15 minutes.
- The potatoes will continue to soften and the flavors will meld together.
- Then scatter the crumbled feta cheese evenly over the surface and roast for an additional 5 minutes until the cheese warms through and just begins to soften but holds its shape.

Ready when: Feta is warmed and slightly softened; potatoes are completely tender when pierced
Tip: Don't overbake the feta or it will become grainy and lose its creamy texture
Rest and finish
- Remove from the oven and let rest for 10–15 minutes before serving.
- This allows the dish to set slightly and the flavors to settle.
- If using fresh oregano, sprinkle it over the top just before serving for a bright, herbaceous note.

Ready when: Dish has cooled slightly and sauce has thickened
Tip: Resting prevents the hot oil from separating and helps the feta hold together
Good to know
Tips
- For deeper flavor, use homemade tomato confit if you have time: roast halved fresh tomatoes at 250°F (120°C) for 2–3 hours with garlic, oregano, and olive oil until they collapse and concentrate.
- If your baking dish is shallow, the potatoes may brown too quickly on top. Tent with foil for the first 30 minutes of roasting, then uncover for the last 5 minutes.
- Taste and adjust seasoning after the feta is added—feta is salty, so you may need less salt than expected.
- Serve warm or at room temperature; Greek food often tastes best when slightly cooled, allowing the oil to coat your palate with every bite.
Make ahead
The tomato confit can be made up to 2 days ahead and stored in the refrigerator in a sealed container. The potatoes are best roasted fresh, but you can prep and cut them up to 4 hours ahead, keeping them in a bowl of cold water to prevent oxidation; drain and pat dry before tossing with oil.
Storage & reheating
Leftovers keep in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 325°F (165°C) oven for 10–12 minutes, covered with foil, or in a microwave-safe dish covered with a damp paper towel for 2–3 minutes. Do not freeze, as the potatoes will become mushy upon thawing.
Substitutions
- canned whole peeled tomatoes → 2 cups (480 ml) fresh crushed tomatoes or tomato sauce. If using fresh tomatoes in season, blanch and peel about 6 medium tomatoes, then crush. The confit will cook slightly faster and have a fresher taste.
- feta cheese → crumbled goat cheese or ricotta salata. Goat cheese will be tangier; ricotta salata is firmer and less salty. Adjust salt in the recipe accordingly.
- dried oregano → 2 tablespoons (6 g) fresh oregano leaves, or 1 tsp each of dried thyme and dried marjoram. Fresh oregano is more delicate; add half to the confit and half as garnish. The thyme–marjoram blend mimics oregano's flavor profile.
- Yukon Gold potatoes → red potatoes or small fingerling potatoes, halved lengthwise. Any waxy potato works; avoid starchy russets, which break apart. Adjust cooking time by 5–10 minutes if using smaller pieces.
