Step‑by‑Step Instructions for Vegan Caramelized Onion Pasta
Step 1: Caramelize Onions
In a large skillet, heat 2 tablespoons of olive oil and 1 tablespoon of optional vegan butter over medium heat. Add 2 sliced large onions, season with salt and pepper, and sauté for about 5 minutes, stirring occasionally. When the onions start to soften, incorporate 2 minced garlic cloves and 1 tablespoon of optional sugar. Pour in 1 cup of water and continue to cook, stirring every so often, for 25–30 minutes until the onions are deeply golden and jammy.
Step 2: Cook Pasta
While the onions are caramelizing, fill a large pot with water, add a generous pinch of salt, and bring it to a boil over high heat. Once boiling, add your choice of pasta and cook until al dente, typically 8–10 minutes. Just before draining the pasta, reserve 1 cup of the starchy cooking water, then drain the rest and set the pasta aside.
Step 3: Make the Sauce
Once your onions are beautifully caramelized, turn the heat to low and stir in seasonings such as smoked paprika, onion powder, garlic powder, dried oregano, and a pinch of chili oil for heat. Slowly incorporate 1 cup of oat cream or your favorite non-dairy cream and ½ cup of vegan Parmesan cheese, allowing the mixture to simmer for 5–7 minutes until the sauce thickens. If needed, adjust the consistency with the reserved pasta water.
Step 4: Combine
Add the drained pasta to the skillet with the caramelized onion cream sauce, gently tossing everything together to ensure the pasta is well coated. Taste and adjust the seasoning if necessary, adding more salt, pepper, or chili oil according to your preference.
Step 5: Serve
Once everything is well combined and heated through, transfer the vegan caramelized onion pasta to serving bowls. Garnish with freshly chopped parsley and additional Parmesan, if desired. Serve hot and enjoy this comforting dish that will please both vegans and non-vegans alike!
