Ever get to the end of the day and realize you need something quick that still feels like real food? These little pea, ricotta, and oat fritters are my go-to when I want a fast dinner, a lunchbox-friendly protein bite, or a “something snacky” to go with a salad. They’re crisp on the outside, tender in the middle, and brightened up with lemon zest and Parmesan.

The key is a quick rest after mixing—just five minutes gives the oats time to hydrate so the batter holds together instead of spreading in the pan. I also like mashing only half the peas: you get enough “glue” for a sturdy fritter, but still keep those sweet green pops of whole peas. They’re ready in about 20 minutes and they reheat surprisingly well.

Why You’ll Love This Recipe

Fast: pantry-friendly ingredients and a quick stovetop cook.
Crispy edges with a soft, creamy center from the ricotta.
Naturally vegetarian and satisfying thanks to oats, egg, and cheese.
Great use for thawed frozen peas (no chopping required).
The 5-minute rest makes the mixture easier to scoop and flip (worth it).
Flexible: works as an appetizer, lunch, or simple dinner.

Ingredients

1 1/2 cups (225 g) green peas, thawed
1 cup (245 g) ricotta cheese, well drained
1 large egg
3/4 cup (75 g) quick oats
1/2 cup (50 g) grated Parmesan cheese
1 teaspoon finely grated lemon zest
1/2 teaspoon kosher salt
1/4 teaspoon black pepper
1 tablespoon (15 ml) olive oil (plus a little more as needed for the pan)

Ingredient Notes

Green peas: Thawed frozen peas are perfect here. Pat them dry if they’re watery—extra moisture can make the mixture loose.
Ricotta: Drain it well. If your ricotta looks wet, spoon it into a fine-mesh strainer (or cheesecloth) for 10 minutes while you prep everything else.
Quick oats: These bind quickly without needing a blender. Old-fashioned rolled oats can work in a pinch, but the texture will be a bit more rustic and the mixture may need an extra minute of resting.
Parmesan: Adds salt and helps the fritters brown. Use finely grated for the best melt and even seasoning.
Lemon zest: Don’t skip it—it makes the peas taste fresher and balances the richness of the ricotta.

Kitchen Tools Needed

Medium mixing bowl
Fork (for mashing peas)
Measuring cups/spoons
Nonstick skillet or well-seasoned cast iron skillet
Thin spatula
Spoon or small scoop for portioning

Step-by-Step Instructions

Thaw and prep the peas.
If your peas are very wet after thawing, pat them dry with a paper towel.
Mash half the peas.
Place about half of the peas in a mixing bowl and mash with a fork until mostly crushed (a few whole ones are fine). This helps the fritters hold together.
Mix the batter.
Add the remaining whole peas, ricotta, egg, quick oats, Parmesan, lemon zest, salt, and pepper. Stir until evenly combined. The mixture should look thick and scoopable.
Rest for 5 minutes.
Let the mixture sit so the oats hydrate. It should firm up slightly and feel less “wet” when scooped.
Heat the pan.
Heat a thin layer of olive oil in a nonstick skillet over medium heat. You want the oil shimmering but not smoking.
Portion and flatten.
Drop heaped spoonfuls of the mixture into the pan (about 2 tablespoons each). Gently flatten into patties about 1/2-inch (1.25 cm) thick so they cook through without burning.
Cook until golden and firm.
Cook for 3–4 minutes per side, flipping carefully once the first side is deeply golden and releases easily from the pan. The fritters should feel set when you press lightly in the center.
Repeat.
Cook in batches so you don’t crowd the pan. Add a drizzle more oil if the pan looks dry between batches.
Serve warm.
They’re best right out of the skillet, when the edges are crisp.

Pro Tips

Drain ricotta well: Wet ricotta is the #1 reason fritters turn soft or spread.
Let the mixture rest: Those 5 minutes make flipping much easier.
Keep the heat at medium: Too hot and the outside browns before the inside sets.
Flatten evenly: A thicker center can stay creamy and undercooked; aim for an even patty.
Wait to flip: If you try too soon, they can break. When they’re ready, they release cleanly.

Common Mistakes

Skipping the rest time, leading to a looser mixture that spreads in the pan.
Using high heat, which can scorch the Parmesan before the fritters are cooked through.
Overcrowding the skillet, which drops the temperature and prevents browning.
Not draining the ricotta, making the batter too wet to hold its shape.
Flipping too early, causing the fritters to fall apart.

Variations

Add herbs: Stir in 1–2 tablespoons chopped fresh parsley, mint, dill, or chives.
Make them a little spicy: Add a pinch of red pepper flakes or a dash of hot sauce.
Swap the citrus: Try orange zest for a slightly sweeter, softer citrus note.
Change the cheese: Pecorino Romano works well (it’s saltier, so reduce salt slightly).

Serving Suggestions

Serve with a dollop of Greek yogurt or sour cream and a squeeze of lemon.
Pair with a simple green salad (arugula is great) for an easy lunch or dinner.
Make them snacky with a dipping sauce like marinara or a quick lemony yogurt sauce.
They’re also lovely alongside roasted tomatoes or a bowl of soup.

Storage Instructions

Let fritters cool completely, then store in an airtight container in the refrigerator for up to 3 days.
For longer storage, freeze in a single layer on a sheet pan, then transfer to a freezer bag/container for up to 2 months.

Reheating Tips

Best: Reheat in a skillet over medium heat with a tiny drizzle of oil, 2–3 minutes per side, until hot and re-crisped.
Oven/toaster oven: 375°F (190°C) for 8–10 minutes.
Microwave: Works in a pinch, but they’ll soften (use short bursts and don’t overheat).

Frequently Asked Questions

Can I use fresh peas instead of frozen?

Yes. Blanch fresh peas in salted boiling water for 1–2 minutes, then drain and cool. You’ll want them tender but not mushy.

What if my mixture feels too wet to scoop?

First, make sure the ricotta was drained. Then let it rest an extra 5 minutes. If it’s still loose, stir in 1–2 tablespoons more quick oats.

Can I bake these instead of pan-frying?

You can, but they won’t get quite as crisp. Bake at 425°F (220°C) on an oiled parchment-lined sheet, flatten into patties, and bake 10–12 minutes, flipping once.

Are these gluten-free?

Only if you use certified gluten-free oats. Everything else is naturally gluten-free.

Can I make the mixture ahead of time?

You can mix it and refrigerate for a few hours. It will thicken as it sits; if it gets very stiff, stir in a spoonful of ricotta or a splash of water before cooking.

Conclusion

If you’ve got a bag of peas and a tub of ricotta hanging around, these fritters are an easy win—quick to make, nicely savory, and crisp in all the right places. Keep them simple with yogurt and lemon, or dress them up with herbs and a dipping sauce. Once you’ve made them once, they’re the kind of recipe you’ll start throwing together without thinking.
