Si el pescado no queda crujiente, lo pondré dos minutos más en el horno.

Because in Spanish, after si for a real, possible condition, you normally use the present indicative, not the future.

So Spanish uses this pattern:

• Si + present, future
• Si el pescado no queda crujiente, lo pondré...

This is the normal equivalent of English If the fish isn’t crispy, I’ll put it...

Using si + future is generally not correct in this type of sentence.

Here quedar means something like to turn out, to end up, or to become in a resulting state.

So el pescado no queda crujiente means:

• the fish doesn’t come out crispy
• the fish doesn’t end up crispy

This is a very common use of quedar when talking about the result of cooking:

• La carne quedó seca = The meat turned out dry
• El pan quedó muy bien = The bread turned out very well

It is not literally just stays here; it is about the final result.

Because quedar focuses on the result after a process.

• ser crujiente would describe something as generally crispy by nature
• estar crujiente describes its current state
• quedar crujiente means it turns out crispy / comes out crispy

In cooking, quedar is especially natural when talking about how food turns out after being cooked.

So in this sentence, quedar is the best choice because the speaker is checking the cooking result.

Lo is a direct object pronoun meaning it, and it refers to el pescado.

• el pescado = masculine singular
• so the pronoun is lo

The full idea is:

• Pondré el pescado dos minutos más en el horno
• but instead of repeating el pescado, Spanish uses lo

So:

• Si el pescado no queda crujiente, lo pondré...
• If the fish isn’t crispy, I’ll put it...

Because object pronouns usually go before a conjugated verb in Spanish.

So:

• lo pondré = I will put it

This is the normal position with a finite verb.

Compare:

• Lo pondré = I will put it
• Voy a ponerlo = I’m going to put it

With an infinitive like poner, the pronoun can attach to the end: ponerlo. But with pondré, it goes before the verb: lo pondré.

The verb is poner = to put.

Its future stem is irregular:

• infinitive: poner
• future stem: pondr-
• pondré = I will put

Many common verbs have irregular future stems in Spanish:

• tener → tendré
• salir → saldré
• venir → vendré
• poder → podré
• hacer → haré

So pondré is just the standard future form of poner.

In Spanish, más comes after the quantity:

• dos minutos más = two more minutes
• cinco euros más = five more euros
• una vez más = one more time / once again

This is the normal word order in Spanish.

So lo pondré dos minutos más means I’ll put it in for two more minutes.

Because en indicates location: in the oven.

• en el horno = in the oven

If you said al horno, that often suggests movement to the oven or forms part of a food description, such as:

• patatas al horno = oven-baked potatoes

In this sentence, the fish is being placed in the oven for more time, so en el horno is the natural choice.

This is a first conditional type of sentence: a real or likely condition in the present/future.

Pattern:

• Si + present indicative, future / command / present

Here:

• Si el pescado no queda crujiente = If the fish doesn’t turn out crispy
• lo pondré dos minutos más en el horno = I’ll put it in the oven for two more minutes

This structure is used for realistic situations.

Because crujiente is an adjective describing pescado.

• el pescado = the fish
• crujiente = crispy

Spanish often uses adjectives directly after verbs like quedar, estar, ser, without an article:

• Está caliente = It’s hot
• Quedó perfecto = It turned out perfect
• No queda crujiente = It doesn’t turn out crispy

So no article is needed before crujiente.

Yes, that is possible, but it means something slightly different.

• Si el pescado no está crujiente... = If the fish is not crispy
• Si el pescado no queda crujiente... = If the fish doesn’t turn out crispy

Está focuses on the fish’s current state. Queda focuses on the result of the cooking process.

In a cooking context, both can work, but queda crujiente sounds especially natural when talking about how the food turns out.

Here pescado means fish as food, not a live fish.

In Spanish, there is often a distinction:

• pez = a live fish
• pescado = fish to eat

Since the sentence talks about putting it in the oven, pescado clearly means the food.

The sentence can be rearranged a little, but the original order is the most natural and neutral.

For example, you could also hear:

• Si no queda crujiente el pescado, lo pondré dos minutos más en el horno.

But this sounds a bit more marked or stylistic. The usual, straightforward version is:

• Si el pescado no queda crujiente, lo pondré dos minutos más en el horno.

So yes, some flexibility exists, but the original sentence is the standard way to say it.
