Ingredients

  • Pasta: 350 g (12 oz) ditalini pasta
  • Onions: 4 large yellow onions, thinly sliced 2 tbsp unsalted butter 1 tbsp olive oil 1 tsp sugar 1/2 tsp salt
  • Sauce: 2 cloves garlic, minced 1 tbsp all-purpose flour 240 ml (1 cup) vegetable broth (or beef broth for non-vegetarian) 120 ml (1/2 cup) heavy cream 1 tsp fresh thyme leaves (or 1/2 tsp dried thyme) 1 tsp Dijon mustard Freshly ground black pepper, to taste
  • Cheese Topping: 100 g (1 cup) Gruyère cheese, grated 40 g (1/3 cup) Parmesan cheese, grated Chopped chives or parsley, for garnish (optional)

Instructions

Step 1:
Cook the ditalini pasta in a large pot of salted boiling water until al dente. Reserve 1/2 cup pasta water, drain, and set aside.
Step 2:
Meanwhile, heat butter and olive oil in a large skillet over medium heat. Add sliced onions, sugar, and salt. Cook, stirring often, until onions are deeply caramelized and golden brown, about 25 30 minutes. Adjust heat as needed to prevent burning.

Add the heavy cream, thyme, Dijon mustard, and black pepper. Simmer gently for 3 4 minutes until creamy.
Step 7:
Stir in the cooked ditalini pasta and reserved pasta water as needed for desired sauce consistency.

Serve hot, topped with remaining Gruyère and fresh herbs.

Recipe FAQs

How do you achieve deep caramelization in the onions?

Cook sliced onions slowly over medium heat with butter and olive oil, stirring often to avoid burning, until they turn a golden brown and develop a rich sweetness, usually about 25–30 minutes.

Can I use other pasta shapes besides ditalini?

Yes, small pasta shapes like elbow macaroni or small shells work well as they hold the creamy sauce effectively.

What broth options enhance the flavor best?

Vegetable broth provides a clean base for vegetarians, while beef broth adds a deeper, savory richness for non-vegetarian versions.

How can I make this dish gluten-free?

Substitute regular ditalini with gluten-free pasta and use gluten-free flour to thicken the sauce, ensuring all other ingredients are gluten-free.

What cheeses can I use as alternatives to Gruyère and Parmesan?

Swiss cheese or a mix of mozzarella and sharp cheddar can be used for a similar creamy and melty texture and rich flavor.

Is it possible to make this dish dairy-free?

Yes, use plant-based cream alternatives and dairy-free cheese substitutes to maintain creaminess without dairy.
