Instructions
Melt butter and oil
Place the cast‑iron skillet over medium‑high heat and add 2 tbsp butter and 1 tbsp olive oil. Let the butter melt, stirring to combine with the oil so the butter doesn’t burn.
Time: PT2M
Sauté onion and bay leaf
Add the diced sweet onion and the bay leaf to the skillet. Sprinkle a pinch of salt and ½ tsp freshly ground black pepper. Cook, stirring occasionally, until the onion is softened and lightly caramelized, about 10 minutes.
Time: PT10M
Add garlic and thyme
Stir in the grated garlic and the stripped thyme leaves. Cook for about 1 minute, just until fragrant; do not let the garlic brown.
Time: PT1M
Toast the pasta
Add the dry anelli pasta to the skillet. Toss continuously for 2 minutes, allowing the rings to get a light golden hue.
Time: PT2M
Deglaze with wine
Pour in 1 cup dry white wine. Let it simmer for about 1 minute, scraping up any browned bits from the pan as the alcohol evaporates.
Time: PT1M
Add flavor bases
Stir in 1 tbsp beef bouillon paste, 1 tsp soy sauce, and ½ tsp Worcestershire sauce. Mix until the paste dissolves completely.
Time: PT1M
Simmer with water
Add 3 cups water, increase the heat to bring the mixture back to a gentle simmer, and cook for 8 minutes, stirring occasionally, until the pasta is al dente and the sauce thickens from the released starch.
Time: PT8M
Finish with crème fraîche and vinegar
Remove the skillet from heat. Stir in 1 tsp crème fraîche and 1 tsp cherry vinegar until fully incorporated, giving the sauce a silky texture and bright note.
Time: PT1M
Broil the cheese topping
Evenly sprinkle the grated Gruyère over the pasta. Pre‑heat the oven broiler on high and place the skillet under it. Broil for about 30 seconds, watching closely, until the cheese bubbles and turns golden‑brown.
Time: PT0.5M
Temperature: high broil
Season and serve
Remove from the oven, discard the bay leaf, and finish with a fresh grind of black pepper. Serve immediately while hot.
Time: PT0.5M

Chef Tips from the Video
- A pinch of salt early helps draw out moisture from the onion, enhancing caramelization
- If you like a deeper flavor, splash an extra ¼ cup wine before adding water
- Mix Gruyère with a bit of sharp white cheddar for extra bite
Troubleshooting
Sauce is too thin
Continue simmering uncovered to reduce, or add a little more crème fraîche for thickness.
Pasta is overcooked and mushy
Cook the anelli al dente in step 7; if overcooked, add a splash of broth and heat briefly to re‑coat.
Cheese becomes oily or doesn’t brown
Use a high‑quality Gruyère and broil only 30 seconds; keep the broiler distance close but not touching the cheese.
Burnt garlic flavor
Add garlic after the onions have softened and stir only 1 minute; lower heat if you hear sizzling.
Storage
Refrigerator: Store leftovers in an airtight container for up to 3 days.
Freezer: Can freeze for up to 2 months; reheat gently on the stovetop with a splash of water.
Room temperature: Do not leave at room temperature longer than 2 hours.
Make-Ahead Tips
- Prepare the onion‑garlic‑thyme mixture and refrigerate for up to 24 hours
- Cook the pasta al dente, rinse, and store in a sealed bag; add to sauce when ready
- Grate the Gruyère in advance and keep covered in the fridge

What regional variations exist for adult mac and cheese dishes in the United States?
Across the U.S., variations include adding smoked meats in the South, using cheddar and pepper jack in the Southwest, or incorporating lobster and truffle oil in upscale coastal versions. This recipe’s French onion twist is a unique Mid‑Atlantic spin.

Bouillon paste provides a concentrated umami boost without adding excess liquid, allowing the sauce to thicken quickly while keeping the flavor deep and savory.
