Per cena voglio impanare le fettine con il pangrattato e poi cuocerle in forno.

This is a very common pattern in Italian.

After verbs like volere (to want), potere (can/to be able to), and dovere (must/have to), Italian usually uses a second verb in the infinitive:

• voglio impanare = I want to bread
• posso cuocerle = I can cook them
• devo comprare il pangrattato = I have to buy breadcrumbs

English often uses to + verb, and Italian does the same idea with the infinitive form of the verb.

Impanare means to coat something in breadcrumbs.

It is a very common cooking verb in Italian. You may also hear panare, which means basically the same thing in many contexts. In everyday Italian, impanare is extremely common when talking about breading meat, fish, or vegetables.

Examples:

• impanare le fettine
• impanare il pollo
• melanzane impanate

So if you are learning everyday kitchen Italian, impanare is a very useful verb.

Italian often uses the definite article where English might not.

So:

• le fettine literally = the slices/cutlets
• in natural English, this may simply be the cutlets or even just cutlets

Italian generally likes to specify nouns with an article, especially when talking about known or specific things:

• compro il pane
• lavo i piatti
• cucino la pasta

Here, le fettine suggests specific slices/cutlets that the speaker has in mind, probably the ones for dinner.

Fettine is the plural of fettina, which is a diminutive form of fetta.

• fetta = slice
• fettina = little slice / thin slice
• fettine = little slices / thin slices

In cooking, fettine often refers to thin slices of meat, especially cutlets or thin veal/chicken slices.

Grammatically:

• singular: la fettina
• plural: le fettine

The ending -ine here marks a feminine plural diminutive.

Pangrattato means breadcrumbs.

It is a single noun formed historically from:

• pane = bread
• grattato = grated

So pangrattato literally means grated bread, but in normal usage it means breadcrumbs.

In the sentence:

• con il pangrattato = with breadcrumbs / using breadcrumbs

The article il is normal here because Italian often uses the article with ingredients and materials:

• con il burro
• con l’olio
• con il formaggio

Because -le is a direct object pronoun meaning them, referring back to le fettine.

So:

• cuocere = to cook
• cuocerle = to cook them

In Italian, object pronouns can attach to an infinitive:

• voglio cuocerle
• devo comprarlo
• posso farla

This is very common after modal or similar verbs.

Here, le is feminine plural because it refers to le fettine:

• la = her/it (feminine singular)
• le = them (feminine plural)

Even though English just says them, Italian shows gender and number in the pronoun.

No. Le cuocere is not correct.

With an infinitive, the pronoun normally attaches to the end:

• cuocerle = correct

If you have a conjugated verb before it, Italian often allows two patterns with certain verbs like volere, potere, and dovere:

• voglio cuocerle
• le voglio cuocere

Both are possible.

But the pronoun cannot go directly before the infinitive by itself:

• le cuocere = incorrect

So in your sentence, cuocerle is perfectly natural.

In forno is a very common Italian expression meaning in the oven in the sense of oven-baked / in an oven.

It often sounds more idiomatic than nel forno when talking about cooking.

Compare:

• cuocere in forno = bake / cook in the oven
• mettere in forno = put in the oven

Nel forno is possible, but it can sound more literal, as if you are emphasizing the physical inside of a specific oven.

So:

• cuocerle in forno = the normal cooking expression
• cuocerle nel forno = possible, but less idiomatic in many contexts

A similar pattern exists in other set expressions in Italian where the article is omitted.

E poi means and then.

It links two actions in sequence:

1. impanare le fettine
2. cuocerle in forno

So the sentence shows the order very clearly:

• first bread them
• then cook them in the oven

You could also hear:

• poi cuocerle in forno
• e dopo cuocerle in forno

But e poi is very natural in everyday speech.

Yes, per cena is a normal and natural way to say for dinner.

It means something like:

• for dinner
• as dinner
• for the evening meal

Examples:

• Per cena faccio la pasta.
• Per cena mangiamo pesce.
• Cosa prepari per cena?

Italian also uses a cena in other contexts, but the meaning is slightly different:

• a cena often means at dinner / for dinner time / to dinner
• per cena focuses more on what is intended as the dinner meal

So in this sentence, Per cena voglio... sounds very natural.

Both cuocere and cucinare relate to cooking, but they are not always interchangeable.

• cucinare = to cook, in the general sense of preparing food
• cuocere = to cook something through, to bake/roast/heat until done

In this sentence, cuocerle in forno is a good choice because it focuses on the actual cooking process in the oven.

Compare:

• Voglio cucinare le fettine = I want to cook/prepare the cutlets
• Voglio cuocerle in forno = I want to cook them in the oven

So cuocere is more precise here.

Yes, it is very natural Italian word order.

The structure is:

• Per cena = context/time-purpose first
• voglio = main verb
• impanare le fettine = first action
• con il pangrattato = how/with what
• e poi cuocerle in forno = second action and where

Italian often puts contextual information like per cena at the beginning. It also likes to keep related pieces together:

• verb + object: impanare le fettine
• prepositional phrase right after: con il pangrattato
• then the next action: e poi cuocerle in forno

So even if English might organize things slightly differently, the Italian sentence sounds smooth and idiomatic.
