Instructions for French Onion Mac and Cheese

Cooking up French Onion Mac and Cheese is as delightful as the dish itself! Follow these steps to create a creamy, cheesy masterpiece that will have everyone coming back for seconds. Each step is filled with aroma and anticipation, leading you to the perfect comfort food.
- Start by boiling your macaroni and cheese according to the package instructions. Make sure to add a pinch of salt to the water for flavor. You’ll want to cook it al dente, as it will continue to cook slightly when combined with the other ingredients.
- While the macaroni is cooking, heat olive oil in a large skillet over medium-high heat. The oil should shimmer but not smoke, which indicates it’s ready for the next step.
- Add the sliced onions to the skillet, along with a sprinkle of salt. Stir them occasionally to ensure even cooking and watch as they turn golden brown and caramelize beautifully. This should take about 10 to 15 minutes.
- Once the onions are caramelized, add in the beef broth and thyme. Stir well and let the mixture simmer, allowing the broth to absorb and reduce slightly. The aroma will be heavenly!
- After the macaroni is done, drain it and return it to the pot. Pour in the cooked onion mixture, stirring to combine everything evenly.
- Now, add the shredded Swiss cheese to the pot, mixing it in until it melts and creates a creamy sauce. If you find it too thick, feel free to add a splash of milk or more broth.
- Once everything is well mixed and creamy, transfer the mac and cheese to a serving bowl or individual plates.
- Finally, top your French Onion Mac and Cheese with some crunchy croutons for that delightful texture contrast. Serve immediately while it’s warm and gooey!
- Enjoy your flavorful culinary creation with your family or friends, and watch as they savor every cheesy bite!
Things Worth Knowing
- Caramelization is Key: The longer you cook the onions, the sweeter and more flavorful they become. Don’t rush this step; patience is rewarded!
- Cheese Selection: Using a good quality Swiss cheese will enhance the creaminess and flavor. Experiment with a blend if you’d like!
- Cooking Pasta: Always cook your macaroni al dente, as it will absorb some moisture from the cheese sauce and continue to cook.
