Are they all correct? ​No. None is correct.

She is a cook and specialized in (baking) pizza.
She is a cook and specialized with (baking) pizza.
She is a cook and specializing in (baking) pizza.
She is a cook and specializing with (baking) pizza.

- Best: She is a cook who specializes in pizza.

- Okay but not as natural: She is a cook specializing in pizza.

It's fine but not necessary to add "baking" to both.

I think my 2nd and 4th sentences are wrong due to "with" but why are #1 and #3 also wrong?
Would "specialized" work in a sentence about the past?
For example, "She was a cook specialized in pizza"?

Simplest is often best: She is a pizza cook.

Yes. Or pizza baker.

She is a cook and specialized in pizza. It's grammatical but means that although she still bakes, she has stopped specializing in pizza.

She is a cook and specializing in pizza. Either add is or get rid of and:

- She is a cook and is specializing in pizza.
- She is a cook specializing in pizza.

She was a cook specialized in pizza. Add who and you're there:

- She was a cook who specialized in pizza.

Are you working on using "specialize" in sentences? It's not really natural in your examples. If we were using a form of "special," Americans would usually say something like "She's a cook. Pizza is her specialty."

(The British say speciality.)

A person who makes pizzas in a pizzeria is a "pizzaiolo/pizzaiola".

She's a pizzaiola.
