Jeg gider ikke at lave aftensmad i aften, så vi spiser rugbrød.

Not exactly.

Gide often means something like:

• feel like
• can be bothered to
• have the energy/motivation to

So Jeg gider ikke at lave aftensmad is not just I don’t want to make dinner. It often suggests:

• lack of energy
• lack of enthusiasm
• mild annoyance
• not feeling up to it

Compare:

• Jeg vil ikke lave aftensmad = I don’t want to make dinner / I refuse to make dinner
• Jeg gider ikke lave aftensmad = I can’t be bothered to make dinner / I don’t feel like making dinner

For learners, gide is one of those very common everyday Danish words that does not translate neatly into one single English verb.

Because in a normal Danish main clause, the finite verb usually comes early, and ikke typically comes after it.

So:

• Jeg gider ikke ...

is the normal word order.

A useful comparison:

• Jeg gider ikke at lave aftensmad.
  main clause
• ... fordi jeg ikke gider at lave aftensmad.
  subordinate clause

In the subordinate clause, ikke comes before the verb more easily because the word order changes.

So the placement of ikke here is completely standard Danish main-clause word order.

Yes, both are possible.

You can say:

• Jeg gider ikke at lave aftensmad
• Jeg gider ikke lave aftensmad

Both are natural Danish.

The version with at can sound a little more explicit or slightly more careful in style, while the version without at is also very common in everyday speech.

Also, lave is a very general verb meaning make/do, and in food contexts it often means cook/prepare:

• lave mad = cook / make food
• lave aftensmad = make dinner

Because meal words often appear without an article in Danish when you mean the meal in a general sense.

So Danish commonly says:

• spise morgenmad
• lave frokost
• lave aftensmad

This is similar to how English often says have breakfast without a.

You would use an article if you were talking about a specific dinner:

• Aftensmaden er klar. = The dinner is ready.
• Vi spiste en god aftensmad. = We ate a good dinner.

But in lave aftensmad, no article is normal.

A little, but it is still natural.

They do different jobs:

• aftensmad = the meal, dinner/evening meal
• i aften = the time, tonight

So the sentence literally says something like:

• I don’t feel like making dinner tonight

The repetition of the evening idea is not strange in Danish. Still, Danish speakers could also shorten it, for example:

• Jeg gider ikke lave mad i aften, så vi spiser rugbrød.
• Jeg gider ikke lave aftensmad, så vi spiser rugbrød.

All of these are natural.

Yes.

• lave mad = cook / make food
• lave aftensmad = make dinner specifically

So:

• Jeg gider ikke lave mad i aften sounds a bit broader.
• Jeg gider ikke lave aftensmad i aften is more specific: it is the evening meal that the speaker does not want to prepare.

In everyday speech, lave mad is extremely common.

Because rugbrød is being used as a mass noun here, like a food type.

So:

• vi spiser rugbrød = we’re eating rye bread / having rugbrød

This does not mean one specific whole loaf. It means that rugbrød is what they are having as food.

If you meant a specific loaf, you could say:

• et rugbrød = a loaf of rye bread

But in meal contexts, Danish often uses food words without an article:

• Vi spiser pasta
• Vi spiser suppe
• Vi spiser rugbrød

Literally, rugbrød is Danish rye bread: dark, dense, and very common in Denmark.

In a sentence like this, vi spiser rugbrød often means more than just we eat plain bread. It usually suggests a simple meal based on rye bread, often with toppings.

So culturally, it may imply something like:

• open-faced rye bread sandwiches
• a simple, easy evening meal
• something quicker than cooking a full hot dinner

That is why it makes sense after I don’t feel like making dinner tonight.

Because Danish often uses the present tense for the near future when the context makes the time clear.

Here, i aften and the overall meaning make it clear that this is about what they are going to do later.

So:

• så vi spiser rugbrød

means something like:

• so we’re having rugbrød
• so we’ll eat rugbrød

This is very normal in Danish, just as English often says:

• We’re eating at home tonight.

instead of

• We will eat at home tonight.

Here så means so / therefore.

In this sentence, it is being used to connect two clauses:

• Jeg gider ikke at lave aftensmad i aften
• vi spiser rugbrød

That gives:

• ..., så vi spiser rugbrød.

This is a normal way to express consequence.

You may also see or hear:

• ..., så spiser vi rugbrød.

That version treats så more like a sentence-opening adverb meaning then/so, which triggers inversion.

So both patterns exist in Danish, but they are not quite the same structurally:

• så vi spiser ... = conjunction-like so
• så spiser vi ... = clause-initial so/then with inversion

The version in your sentence is perfectly natural.

Because the sentence contains two main clauses:

• Jeg gider ikke at lave aftensmad i aften
• vi spiser rugbrød

They are linked by så, and in written Danish it is normal to separate such clauses with a comma.

So the comma helps show the structure:

• first clause: the reason/situation
• second clause: the result

In other words:

• I don’t feel like making dinner tonight, so we’re having rugbrød.

That is exactly the kind of place where Danish normally uses a comma.
