Step-by-Step Instructions
- Caramelize the Onions:
- Slice the onions into even quarter inch pieces so they cook evenly and reveal sweet notes. Heat butter and olive oil in a skillet over medium. Add onions stirring to coat. Keep heat gentle and stir every few minutes for up to fifty minutes. You want them soft golden brown and full of flavor. If they start to brown too fast drop the heat and stir often. Once they’re a deep caramel hue set aside
- Cook the Bacon:
- Cut the bacon strips into thirds. This makes them easier to flip and brown evenly. Place in a heavy skillet over low heat and cook slowly to render out fat and get that signature crispness. Flip as needed. Once done remove to a paper towel lined plate and save four tablespoons of the bacon fat for the next step.
- Make the Sauce and Cook the Pasta:
- While bacon cooks get water boiling for pasta. Salt it generously for flavor. In the bacon drippings over medium add flour. Whisk for two minutes to cook off the raw taste. Slowly drizzle in the heavy cream whisking all the while so the sauce becomes smooth. Add milk in the same careful way to avoid lumps. Sprinkle in the mustard powder dried thyme garlic powder and hot sauce. Stir and let the mixture come to a simmer.
Cook the pasta shells until just al dente check the package for timing. Drain well.
Once the sauce is hot but not boiling lower the heat and gently stir in shredded cheeses a little at a time so it melts without clumping. Add caramelized onions and drained pasta folding gently to coat.
Chop the crispy bacon sprinkle most on top and stir some into the mac for smoky bites throughout. Finish with a sprinkle of fresh herbs like parsley if desired.

My favorite part is always the Gruyere. That nutty rich melt factor is irreplaceable and every time my mom visits she picks out extra Gruyere bites from the pan just like I used to as a kid. We both agree it makes this recipe extra special.
Storage Tips
Once cooled spoon leftovers into an airtight container and stash in the fridge. It keeps well for up to three days and reheats creamy after a gentle zap in the microwave. For make ahead freezer meals portion out into small containers. While the cream sauce may separate a little with freezing it is still absolutely worth doing for an easy treat.
Ingredient Substitutions
If you are out of Gruyere you can use all cheddar or a mix of cheddar and Monterey Jack for a slightly milder melt. No pasta shells on hand Try elbow macaroni or cavatappi since their curves hold sauce perfectly. Smoked turkey or ham works well for a pork-free twist.
Serving Suggestions
This dish shines on its own but I love pairing it with a crisp green salad or simply steamed broccoli to balance the richness. For a more filling meal serve with roasted chicken or grilled sausages on the side. If you want it as a side dish try it with barbecue or baked beans.
