Marinara vs. Bolognese

I think one of the distinguishing characteristics of adulthood is realizing that there is more than one kind of red pasta sauce.

For example, marinara is not bolognese, which is not pizza sauce. Gone are the days of college, where red sauces can be used interchangeably without care.

These days, with your sophisticated palette, you can appreciate the finer points of pasta sauce. That’s not to say it’s wrong to make whatever you have handy work in a pinch.

No, the difference now is that you realize you’re going to get a slightly runny pizza if you use marinara on top of your almond-flour crust.

So what is the difference between marinara and bolognese?

Many distinguish bolognese from marinara because the latter doesn’t include meat. But that definition gets a little fuzzy when you find instances of “meat marinara” on shelves and menus.

Bolognese is really meaty. The proportion of meat and sauce is totally different than a marinara sauce.

Bolognese is heavy on the meat, light on the sauce. Most marinaras don’t include meat at all, and the ones that do include it as an accessory rather than the main feature.

Marinara is typically enjoyed over thin strands of spaghetti, while bolognese pairs well with a thicker, more ribbon-like noodle.

Creating bolognese is typically quite a production. In addition to meat, the sauce can contain wine, milk or cream, tomato paste, and soffritto, which is onion, celery, and carrot.

Getting it right can be a lengthy undertaking.

How to Make this Keto

Making this bolognese Keto is pretty simple. The major factor in this dish isn’t the sauce – it’s the “pasta” that serves as the foundation.

For this dish, I went with zucchini to sub for grain-based pasta. You can use a peeler to get long, flat strands, or a spiralizer, which will get you closer to spaghetti.

I also left out the dairy element that is often present in bolognese. It’s not necessary, and the omission is helpful for the many people who don’t tolerate dairy well.
