Sutra ću skuhati rižu s povrćem za večeru.

Ću is the 1st person singular form of the auxiliary used to make the future tense.

So:

• ću = I will
• skuhati = to cook / to cook completely

Together, ću skuhati means I will cook.

The full future-tense set is:

• ću = I will
• ćeš = you will
• će = he/she/it will
• ćemo = we will
• ćete = you (plural/formal) will
• će = they will

Croatian usually forms the future with two parts:

1. a form of the auxiliary htjeti in its short form
2. the infinitive of the main verb

So:

• ću skuhati = I will cook
• literally, something like will cook

This is normal Croatian structure. English uses a subject plus will plus a bare verb; Croatian uses a clitic auxiliary plus the infinitive.

Also, Croatian often places short words like ću in the second position of the sentence, which is why Sutra ću skuhati... sounds natural.

This is a very common Croatian question because it involves aspect.

• kuhati = imperfective: to cook, to be cooking, to cook in general
• skuhati = perfective: to cook something completely, to finish cooking it

In this sentence, the speaker means a completed future action: tomorrow they will cook the rice and have it ready. That is why skuhati fits very well.

Compare:

• Sutra ću kuhati. = Tomorrow I’ll be cooking. / Tomorrow I’ll cook.
  (focus on the activity)
• Sutra ću skuhati rižu. = Tomorrow I’ll cook the rice.
  (focus on the completed result)

Because it is the direct object of the verb, so it goes into the accusative case.

Base form:

• riža = rice

Accusative singular:

• rižu

So:

• skuhati rižu = to cook rice

This is a standard pattern for many feminine nouns ending in -a:

• voda → vodu
• juha → juhu
• večera → večeru
• riža → rižu

After the preposition s meaning with, Croatian normally uses the instrumental case.

So:

• povrće = vegetables / vegetable matter
• s povrćem = with vegetables

Here, povrćem is the instrumental singular form.

This is a very useful pattern:

• s prijateljem = with a friend
• s obitelji = with family
• s mesom = with meat
• s povrćem = with vegetables

They both mean with. Sa is mainly used for easier pronunciation before certain sound combinations.

Examples:

• s povrćem = with vegetables
• sa sirom = with cheese
• sa mnom = with me

In your sentence, s povrćem is the normal form.

The preposition za often takes the accusative case. In this sentence, za večeru means for dinner.

Base form:

• večera = dinner

Accusative singular:

• večeru

So:

• za večeru = for dinner

This expression tells you the purpose or occasion of the food.

Compare:

• za doručak = for breakfast
• za ručak = for lunch
• za večeru = for dinner

Sutra means tomorrow. It gives the time of the action.

Croatian often places time expressions near the beginning of the sentence, so:

• Sutra ću skuhati... = Tomorrow I will cook...

That word order is very natural.

Yes. Croatian word order is fairly flexible, although some versions sound more natural than others depending on emphasis.

Your sentence:

• Sutra ću skuhati rižu s povrćem za večeru.

Possible alternatives:

• Rižu s povrćem ću skuhati sutra za večeru.
• Za večeru ću sutra skuhati rižu s povrćem.
• Sutra ću za večeru skuhati rižu s povrćem.

The meaning stays very similar, but the focus shifts slightly.

One important rule: short forms like ću are clitics, so they usually come in or near the second position in the sentence.

Because Croatian often omits subject pronouns when they are not needed.

The form ću already tells you the subject is I. So ja is unnecessary unless you want emphasis.

Compare:

• Sutra ću skuhati rižu. = Tomorrow I’ll cook rice.
• Ja ću skuhati rižu. = I will cook rice.
  (more emphasis on I)

This is very normal in Croatian.

No—Croatian does not have articles like English a/an and the.

So Croatian simply says:

• rižu = rice / the rice
• večeru = dinner / the dinner

The exact meaning depends on context. English learners often look for an article, but Croatian just does not use one.

Yes, that is the most natural reading.

• riža s povrćem = rice with vegetables

It sounds like one combined dish or rice served together with vegetables. In context, it would normally mean a meal based on rice and vegetables.

A few useful pronunciation notes:

• ć is a soft sound, somewhat like a very soft ch/t sound
• ž sounds like the s in measure
• č and ć are different sounds in Croatian, though many learners need time to hear the difference clearly

Rough guides:

• ću ≈ soft tyoo / chyoo
• rižu ≈ REE-zhu
• povrćem ≈ POVR-tyem

Also, Croatian spelling is very regular, so once you learn the letters, pronunciation becomes much easier than in English.

Yes, it sounds perfectly natural.

Sutra ću skuhati rižu s povrćem za večeru. is a straightforward everyday sentence with:

• a time word: sutra
• future tense: ću skuhati
• direct object in accusative: rižu
• s
  • instrumental: s povrćem
• za
  • accusative: za večeru

So it is a very useful model sentence for learning several important Croatian patterns at once.
