What would be a good mix of herbs to season this dish?

Cayenne pepper for kick, mustard powder for flavour, and some minced chives would be my recommendation. Perhaps a dash of turmeric. Some minced horseradish would probably be good too.

To add to @SmashTheState‘s recommendations: paprika or a smoked paprika would add an interesting flavour.

You might add some sweet pickle relish, lemon juice and a bit of hot sauce. Sprinkle a bit of paprika on top for color.

All good suggestions. As far as balancing the flavors, add a little of each at a time until they taste right to you. If you don’t have any chives, maybe a little mild fresh onion finely chopped.

Garlic powder.

Am I the only one to think basil??

@jazmina88 No, I was planning to suggest basil along with a slight onion flavor. Chives or shallots.

You could also add a teeny tiny splash of Balsamic vinegar (no more than a quarter of a teaspoon) with some chopped celery, chopped green onions and/or matchstick cut radishes for a bit of a bite and crunch.

For a differerent taste profile, you could add some chopped (fresh) parsley, a Teaspoon up to a Tablespoon, and maybe a pinch of dried dill, about a quarter teaspoon, and maybe some chopped walnuts, a Tablespoon, or instead of the walnuts, some sliced ripe olives, about a Tablespoon.

And for yet another option, you could add in some chopped sundried tomatoes (the kind in the jar packed in oil) about a Tablespoon or even 2 if you really like that flavor, like I do, along with some chopped marinated artichoke hearts.

And last, but not least, you might like about a Teaspoon of those yummy French fried onions, like you put on top of a green bean casserole. Trader Joe’s makes their Own Brand which are far superior in taste, and not so greasy as the French’s brand. I’ve been putting them on everything from sandwiches, to macaroni and cheese and topping my salad with them and eating them on the side, instead of chips. Yum!

All good flavors mentioned here, but the question called for herbs.

The pasta is calling for basil but… Basil and eggs?!? Gross!
With all the dairy you’ve sauced it up with the logical choices would be chive, chervil or tarragon.

@ everyone, thanks all. @Kardamom I don’t have a Trader Joe’s, but I’ll have to try other brands as I find them. I’ve used the French’s but have nothing to compare them to. Sadly from other’s pov I don’t believe in celery, and I won’t be putting that near any of my food.

@DaphneT Some dill weed and or seed would also go well with that dish.
