Instructions

  1. Prep Ingredients

    Peel and slice the onions into half‑inch pieces, roast a whole bulb of garlic, measure all spices, and shred the Swiss cheese.

    Time: PT10M

  2. Heat Ghee

    Set the Ninja Foodi to High Sear/Sauté, add 4 tbsp ghee and let melt, spreading it evenly.

    Time: PT2M

  3. Caramelize Onions

    Add the sliced onions, 1 tsp black pepper, 1 tsp fine sea salt, and 1 tsp dried thyme. Cook on High Sear/Sauté, stirring only every 5‑7 minutes, for about 25 minutes until deep golden‑brown and reduced to roughly 1½‑2 cups.

    Time: PT25M

  4. Reserve Half of the Onions

    Scoop out about half of the caramelized onions (≈1 cup) and set aside for later topping.

    Time: PT2M

  5. Brown the Beef

    Add the thinly sliced beef and 0.5 tsp fine sea salt to the pot. Stir and cook for 3‑4 minutes until the pink disappears.

    Time: PT5M

  6. Add Roasted Garlic and Deglaze

    Toss in the whole roasted garlic bulb. Pour in ¼ cup sherry (or extra beef consomme) and scrape the fond from the bottom.

    Time: PT3M

  7. Add Liquids

    Pour in the 10.5 oz beef consomme, 10.5 oz beef broth, and 10.5 oz canned French onion soup. Stir to combine.

    Time: PT2M

  8. Add Pasta

    Add the dry rigatoni, pressing it down so it is mostly submerged in the liquid.

    Time: PT2M

  9. Pressure Cook

    Seal the lid, set to High Pressure, and cook for 4 minutes. Allow a natural release for 2 minutes, then quick‑release any remaining pressure.

    Time: PT8M

  10. Finish and Season

    Open the pot, stir gently, return the reserved onions, and taste. Adjust salt, pepper, or thyme as needed.

    Time: PT3M

  11. Add Cheese and Croutons

    Evenly sprinkle the shredded Swiss cheese, lay the provolone slices on top, and then scatter the croutons.

    Time: PT2M

  12. Crisp/Bake Topping

    Close the crisping lid, select Bake/Roast at 375°F and cook for 20 minutes until the cheese is bubbly and the croutons are golden.

    Time: PT20M

    Temperature: 375°F

  13. Rest and Serve

    Turn off the machine, let the casserole rest for 5 minutes, then serve hot, scooping from the bottom to get pasta, beef, onions, and crunchy topping in each bite.

    Time: PT5M

What are the most common mistakes to avoid when making French Onion Pasta Casserole?

A

Common errors include under‑caramelizing the onions, over‑cooking the pasta during pressure cooking, and adding too much liquid, which can make the dish soupy. Also, forgetting to add the reserved onions at the end can result in a loss of texture.

technical
Q

Why does this French Onion Pasta Casserole recipe use pressure cooking instead of stovetop simmering?

A

Pressure cooking dramatically reduces the time needed for the pasta to absorb the flavorful broth while still allowing the onions and beef to stay tender. It also helps the sauce thicken quickly, creating a cohesive casserole texture.

A

Yes. Assemble the casserole up to the cheese and crouton topping, then refrigerate for up to 24 hours. When ready to serve, add the topping and crisp/bake for 20 minutes. Leftovers keep in the fridge for 3 days or freeze for up to 2 months.
