Ingredients

0/12 ready
  • 4 cups stale bread, crusts removed and torn into chunks
  • 1 cup whole milk
  • 2 cups leftover roasted vegetables (any combination of peppers, zucchini, eggplant, tomatoes)
  • 2 large eggs, beaten
  • 1 1/2 cups all-purpose flour, plus more for dusting
  • 1/2 cup grated Parmesan cheese
  • 3 cloves garlic, minced
  • 1/4 cup olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • Fresh basil leaves for garnish
  • Extra Parmesan for serving

The Story & Steps

There's something deeply satisfying about rescuing food from the brink of the bin. That rock-hard baguette on your counter? It's not garbage—it's opportunity in disguise. Combined with those slightly sad roasted vegetables from last night's dinner, you're about to create gnocchi that would make an Italian grandmother pause and ask for the recipe.

Making the Gnocchi

Step 1: Place your stale bread chunks in a large bowl and pour the milk over them. Let this sit for 15-20 minutes until the bread has absorbed all the liquid and become completely soft. This is the magic moment where stale becomes spectacular.

Step 2: Using your hands or a potato masher, squeeze and mash the bread mixture until it forms a relatively smooth paste. A few lumps are fine—they'll add character. Mix in the beaten eggs, Parmesan, salt, and pepper until well combined.

Step 3: Gradually add the flour, stirring with a wooden spoon until a sticky dough forms. The dough should be soft but manageable. If it's too wet, add flour a tablespoon at a time; if too dry, add a splash of milk.

Step 4: On a well-floured surface, divide the dough into four portions. Roll each portion into a long rope about 3/4-inch thick. Cut into 1-inch pieces. If you're feeling fancy, roll each piece down the back of a fork to create those classic gnocchi ridges.

Preparing the Veggie Sauce

Step 5: Roughly chop your leftover roasted vegetables into bite-sized pieces. In a large skillet, heat the olive oil over medium heat and sauté the minced garlic for about 1 minute until fragrant.

Step 6: Add the chopped roasted vegetables to the skillet. Using the back of your spoon, mash about half of them to create a chunky sauce, leaving the rest intact for texture. Season with additional salt and pepper to taste. Keep warm on low heat.

Cooking and Serving

Step 7: Bring a large pot of salted water to a gentle boil. Working in batches, drop the gnocchi into the water. They're done when they float to the surface—usually about 2-3 minutes. Use a slotted spoon to transfer them directly to the skillet with the veggie sauce.

Step 8: Toss the gnocchi gently in the sauce over medium heat for 2-3 minutes, allowing them to absorb the flavors and develop a slight golden crust on the bottom.

Serve immediately with a generous shower of fresh Parmesan and torn basil leaves. Each bite is a testament to resourcefulness: tender pillows of bread-gnocchi coated in a rustic sauce that honors yesterday's dinner. This is the kind of cooking that makes you feel clever, satisfied, and just a little bit smug about your zero-waste kitchen prowess.
