View list

Instructions

  1. 01

    Cook the vegetables. Heat oven to 375°F (190°C). In a 10-inch oven-safe skillet, soften onion in oil over medium heat for about 5 minutes. Add spinach and cook until wilted; let excess moisture evaporate.

  2. 02

    Add the eggs. Whisk eggs, cheese, salt and pepper. Spread vegetables evenly and pour in eggs. Cook gently on the stove about 2–3 minutes until the edges begin to set.

  3. 03

    Finish safely. Transfer using oven mitts to the oven and bake about 10–15 minutes until set and the center reaches 160°F (71°C). Check with a thermometer. Keep a mitt over the hot handle after removing.

  4. 04

    Portion. Let stand briefly and cut into four wedges. Refrigerate leftovers promptly and reheat throughout to 165°F (74°C).

Larry’s rule: Cook off spinach water before adding eggs; check the center, not just the edges.

Before you cook

What to know about Spinach Frittata

What it is

Spinach Frittata is a breakfast recipe rooted in Italian home cooking. This version makes 4 servings in 35 min and focuses on the technique that gives the dish its characteristic texture and flavor.

Why this method works

The method builds flavor in a deliberate order: cook the vegetables, then add the eggs, then finish safely. Following that sequence keeps the main ingredients distinct while bringing the finished dish together.

Key ingredients and what they do

  • 6 large eggs — adds richness and helps bind or set the finished dish.
  • 5 oz baby spinach, washed — supports the dish's balance, texture and regional character.
  • 1 small onion, finely chopped — provides the aromatic character; use it at the stage specified so it stays distinct.
  • 2 tablespoons olive oil — builds the savory foundation and carries flavor through the dish.

Smart substitutions

For the most reliable result, keep the main ingredient and technique unchanged. Swap only like for like, then adjust salt, moisture and cooking time to taste.

Make ahead and leftovers

Prepare and measure the ingredients ahead, then cook close to serving for the best texture.

What to serve with it

  • Serve hot with coffee and fresh fruit.
  • Round it out with bread or a simple salad for brunch.

Serving and substitutions

Cook off spinach water before adding eggs; check the center, not just the edges. Follow the measured recipe first; substitutions change texture and timing. Review all ingredients for allergies. Serve rice as a main, bread and salad alongside a main, and sauces in quantities suited to the dish.

Preparation and storage

Refrigerate perishable ingredients promptly and use cooked leftovers within 3–4 days at 40°F or below. Reheat cooked leftovers throughout to 165°F; cold salads and yogurt bowls are served cold, not claimed to reheat well.

Red Pepper or Green Pepper

A rain-slicked city, two agents in leather, and a man in a chair offering Larry the choice every cook eventually faces: red pepper or green pepper. He takes both, and the sausage starts falling like code.

Quick answer

What Italian drinks should I serve at a dinner party?

Follow the meal: open with an aperitivo such as an Aperol or Campari spritz or Prosecco, pour a white or light red with antipasti and pasta, a fuller red like Chianti Classico with meat, then espresso and a digestivo such as limoncello or amaro. Offer a bitter soda spritz as a zero-proof option.
