Hun finner vispen i skuffen og setter stekebrettet i ovnen.

Those endings mark the definite form of the noun, like the in English.

So:

• visp = a whisk

• vispen = the whisk

• skuff = a drawer

• skuffen = the drawer

• stekebrett = a baking tray

• stekebrettet = the baking tray

• ovn = an oven
• ovnen = the oven

In Norwegian, definiteness is often added to the end of the noun instead of using a separate word like the.

A very rough pattern is:

• masculine/common nouns often take -en
• neuter nouns often take -et

So stekebrettet ends in -et because stekebrett is a neuter noun.

Hun is the subject form of she, while henne is the object form of her.

In this sentence, she is the one doing the actions:

• Hun finner ...
• (Hun) setter ...

So you need hun.

Compare:

• Hun finner vispen. = She finds the whisk.
• Jeg ser henne. = I see her.

Because the subject is the same in both parts of the sentence, Norwegian often leaves it out after og.

So:

• Hun finner vispen i skuffen og setter stekebrettet i ovnen.

means the same as:

• Hun finner vispen i skuffen og hun setter stekebrettet i ovnen.

The version without the second hun sounds more natural here.

English does this too sometimes:

• She finds the whisk and puts the baking tray in the oven.

They are both in the present tense.

• finner = finds
• setter = puts / places / sets

The infinitives are:

• å finne = to find
• å sette = to put / set / place

This kind of sentence is very common in Norwegian instructions, descriptions, and everyday narration, even when English might also use the present tense.

Because i usually means in.

So:

• i skuffen = in the drawer
• i ovnen = in the oven

In the first part, it shows where the whisk is found. In the second part, it shows where the baking tray is placed.

Norwegian often uses i where English uses in.

Sometimes learners expect inn i for movement, and that is possible when you want to emphasize movement into something:

• Hun setter stekebrettet inn i ovnen.

But in everyday Norwegian, setter ... i ovnen is completely normal.

Both verbs can relate to putting something somewhere, but they are not always interchangeable.

• å sette is often used for putting something in an upright, placed, or positioned way
• å legge is often used for laying something down

With objects like trays, pans, and similar kitchen items, Norwegian often uses sette quite naturally, even when English simply says put.

So:

• setter stekebrettet i ovnen = puts the baking tray in the oven

You may also hear legger stekebrettet i ovnen in some contexts, but setter is very natural here.

Stekebrettet is the definite form of stekebrett, which usually means the baking tray or the oven tray.

It is made from:

• steke = to roast / fry / bake with heat
• brett = tray

So stekebrett is literally something like a tray used for cooking in the oven.

Depending on context, English might translate it as:

• the baking tray
• the baking sheet
• the oven tray

In Bokmål, both can exist depending on style and gender choice.

Skuff can be treated as:

• a masculine/common noun: skuffen
• or in many cases a feminine noun: skuffa

So both of these may be seen:

• i skuffen
• i skuffa

For many learners, skuffen is the safest form to recognize and use, because common-gender forms are widely accepted in Bokmål.

That is just a basic feature of Norwegian grammar.

English says:

• the whisk
• the drawer
• the oven

Norwegian often says:

• vispen
• skuffen
• ovnen

The idea of the is built into the noun ending.

Sometimes Norwegian can also use a separate determiner together with the definite noun, but usually only when there is an adjective:

• den store ovnen = the big oven

Without an adjective, you normally just use the noun with the definite ending:

• ovnen = the oven

A simple way to see it is:

• Hun = subject
• finner = verb
• vispen = object
• i skuffen = prepositional phrase

and then:

• og
• (hun) = understood subject
• setter = verb
• stekebrettet = object
• i ovnen = prepositional phrase

So the pattern is basically:

Subject + verb + object + place

That is very similar to normal English word order in a sentence like this.

Very literally, it is:

She finds the whisk in the drawer and puts the baking tray in the oven.

The structure is actually quite close to English, which is helpful for learners.

The main things that differ are:

• Norwegian marks the with noun endings: vispen, skuffen, stekebrettet, ovnen
• the second she is omitted after og
• setter covers the meaning of English puts / sets / places

So even though the sentence looks different in detail, its overall structure is quite familiar to an English speaker.
