Deep Dive into Ingredients

  • Pasta: Any type works; each brings its own charm and texture.
  • Onions and Garlic: They are the heart of this dish, providing a depth of sweet, savory flavor.
  • Cream Cheese (Plant-Based): For that luscious, creamy texture without the heaviness.
  • Seasonings and Olive Oil: These enhance the dish, highlighting the natural flavors of the main ingredients.
  • Lentils or Chickpeas: An optional addition for those seeking an extra punch of protein.

Cooking Tips for Perfection

  • Caramelization is Key: The slow caramelization of onions unlocks their natural sweetness and is central to the flavor profile of this dish.
  • Roast the Garlic to Perfection: Roasted until golden and soft, garlic offers a complex, sweet, and less pungent flavor.
  • Al Dente Pasta: Cook your pasta just right – it should be firm to the bite and able to hold the creamy sauce effectively.

Step-by-Step Guide

  • Begin with Onions and Garlic: Lay your sliced onions on a baking tray. Mix in your seasonings – salt, paprika, garlic powder, onion powder, black pepper, cayenne pepper, and dried oregano. Drizzle with olive oil and toss to coat evenly. Nestle dollops of plant-based cream cheese and a whole garlic bulb among the onions.
  • Roasting: Cover the tray with foil and roast in a preheated oven at 482°F (250°C) for about 1 hour. The goal is for the onions to turn golden and the garlic to soften.
  • Finishing the Roasted Mix: Once done, squeeze the roasted garlic out of its skin back onto the tray. Stir in dried tomatoes and chopped parsley for freshness, and add a dash of balsamic glaze for a tangy sweetness.
  • Pasta Timing: Start cooking your pasta when the onions have about 10 minutes left in the oven. Aim for al dente; it should be ready just as the onions are perfectly caramelized.
  • Combining Everything: Fold the freshly cooked pasta into the tray of caramelized onions and garlic. Mix well, ensuring the pasta is evenly coated with the creamy, flavorful mixture.
